Peter throws a snowball at his car parked in the driveway. The snowball disintegrates as it hits the car. By Newton's third law, you know that both the car and the snowball exert a force on each other. What can you say about the magnitude of the forces exerted by the snowball and the car?
Answer:
The answer is A.
Explanation:
The force exerted by the car is more than the force exerted by the snowball.
Answer:
In the given case, the force applied by the car is equivalent to the force applied by the snowball. According to Newton's third law of motion, when an object employs a force on the other object, then the other object applies an equivalent and opposite force on the first object, and the law also considers that the two forces are also similar in magnitude and are opposing in direction.
In the mentioned question, it is considered that the force is applied by the snowball on the car, thus, it can be termed as the action force. Thus, the force employed by the car on the snowball is the reaction, and according to Newton's third law, the two forces are similar in magnitude, and thus, the force applied by the car is equivalent to the force applied by the snowball.

If a sample has a mass of 1.25⋅102 g and a volume of 51 mL, what is its density?
Answer:
2.5 g/mlExplanation:
1) Data:
a) m = 1.25 × 10² g
b) V = 51 ml
d) density = ?
2) Principles and formulae:
Density is a concentration unit that tells the ratio of the mass of a substance to its volume.
Equation: d = m / VWhere d is the density of the substance, m is the mass, and V is the volume.
3) Solution:
a) Substitute the data into the equation:
d = m / V = 1.25 × 10² g / 51 ml = 2.45 g/ml.b) Use the correct number of significant digits: 2.45 g/ml must be rounded to two signficant figures, i.e. to 2.5 g/ml, since the volume was given with two significant digits.
Fusion reactions constitute the fundamental energy source of stars, including the Sun. Hydrogen “burning” initiates the fusion energy source of stars and leads to the formation of helium. Generation of fusion energy for practical use also relies on fusion reactions between the lightest elements that burn to form helium. In fact, the heavy isotopes of hydrogen—deuterium and tritium—react more efficiently with each other, and, when they do undergo fusion, they yield more energy per reaction than do two hydrogen nuclei. The hydrogen nucleus consists of a single proton. The deuterium nucleus has one proton and one neutron, while tritium has one proton and two neutrons.
What conclusion can be drawn from this information?
A)
Deuterium and tritium are required to burn hydrogen.
B)
The most efficient fusion reactors would use two hydrogen nuclei.
C)
The most efficient fusion reactors would use heavier forms of hydrogen.
D)
Helium occurs naturally. The burning of hydrogen is not required to get helium in nature.
Answer:
C) The most efficient fusion reactors would use heavier forms of hydrogen.
Explanation:
From the information presented to us in the question, the third sentence reveals that heavier forms of hydrogen produces larger amount of energy and most importantly reacts more efficiently when fusion occurs.
In fact, the heavy isotopes of hydrogen—deuterium and tritium—react more efficiently with each other, and, when they do undergo fusion, they yield more energy per reaction than do two hydrogen nuclei.
What is the mole ratio of c4h10 to co2 in the reaction 2C4H10+13O2->8CO2+10H2O??
Answer:
The mole ratio of C₄H₁₀ and CO₂ is 2 : 8, which simplifies to 1 : 4.Explanation:
The mole ratio is the relative proportion of the moles of products or reactants that participate in the reaction according to the chemical equation.
The chemical equation given is:
2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂OOnce you check that the equation is balanced, you can set the mole ratios for all the reactants and products. The coefficients used in front of each reactant and product, in the balanced chemical equation, tells the mole ratios.
In this case, they are: 2 mol C₄H₁₀ : 13 mol O₂ : 8 mol CO₂ : 10 mol H₂O
Since you are asked about the mole ratio of C₄H₁₀ and CO₂ it is:
2 mol C₄H₁₀ : 8 mol CO₂ , which dividing by 2, simplifies to 1 mol C₄H₁₀ : 4 mol CO₂, or 1 : 2.tert-Butyl alcohol is a solvent with a Kf of 9.10 ∘C/m and a freezing point of 25.5 ∘C. When 0.807 g of an unknown colorless nonelectrolyte liquid was dissolved in 11.6 g of tert-butyl alcohol, the solution froze at 15.3 ∘C.Which of the following is most likely the identity of this unknown liquid? View Available Hint(s) tert-Butyl alcohol is a solvent with a of 9.10 and a freezing point of 25.5 . When 0.807 of an unknown colorless nonelectrolyte liquid was dissolved in 11.6 of tert-butyl alcohol, the solution froze at 15.3 .Which of the following is most likely the identity of this unknown liquid? ethylene glycol (molar mass = 62.07 g/mol) 1-octanol (molar mass = 130.22 g/mol) glycerol (molar mass = 92.09 g/mol) 2-pentanone (molar mass = 86.13 g/mol) 1-butanol (molar mass = 74.12 g/mol)
Answer:
ethylene glycol (molar mass = 62.07 g/mol).
Explanation:
We can solve this problem using the relation:ΔTf = Kf.m,
ΔTf is the depression in the freezing point of tert-Butyl alcohol (ΔTf = freezing point of pure solvent - freezing point in presence of unknown liquid = 25.5°C - 15.3°C = 10.2°C).
Kf is the molal freezing point constant of tert-Butyl alcohol (Kf = 9.1 °C/m).
m is the molality of unknown liquid.
∵ ΔTf = Kf.m
∴ m = ΔTf/Kf = (10.2°C)/(9.1 °C/m) = 1.121 m.
We need to calculate the molar mass of the unknown liquid:Molality (m) is the no. of moles of solute in 1.0 kg of solvent.
∴ m = (mass/molar mass) of unknown liquid/(mass of tert-Butyl alcohol (kg))
m = 1.121 m, mass of unknown liquid = 0.807 g, mass of tert-Butyl alcohol = 11.6 g = 0.0116 kg.
∴ molar mass of unknown liquid = (mass of unknown liquid)/(m)(mass of tert-Butyl alcohol (kg)) = (0.807 g)/(1.121 m)(0.0116 kg) = 62.06 g/mol.
So, the unknown liquid is:
ethylene glycol (molar mass = 62.07 g/mol).

Final answer:
Using Graham's law, we find that hydrogen effuses twice as fast as helium. Since a helium-filled balloon takes 6 hours to deflate by 50%, a hydrogen-filled balloon will take 3 hours to deflate to the same percentage under identical conditions.
Explanation:
The question refers to the concept of effusion of gases, which is covered under the topic of kinetic molecular theory in chemistry. The rate of effusion of a gas can be described by Graham's law, which states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. Given that helium gas takes 6 hours to deflate to 50% of its original volume, and knowing that hydrogen gas effuses four times faster than oxygen, we can compare the properties of helium and hydrogen to determine how long it should take for a balloon with hydrogen gas to deflate to the same extent under identical conditions.
To find the time it will take for the hydrogen balloon to deflate, we need to use the relative rates of effusion of hydrogen and helium. Given that hydrogen has a molar mass of approximately 2 g/mol and helium has a molar mass of approximately 4 g/mol, we can calculate the relative rate of effusion using the formula from Graham's law:
Rate of effusion (helium) / Rate of effusion (hydrogen) = sqrt(Molar mass of hydrogen) / sqrt(Molar mass of helium)
Rate of effusion (helium) / Rate of effusion (hydrogen) = [tex]\sqrt{2}[/tex] / [tex]\sqrt{4}[/tex]
This means that the rate of effusion for helium is half that of hydrogen. Since effusion rate is inversely related to the time taken, if helium takes 6 hours to effuse 50%, hydrogen, which effuses twice as fast, will take half the time. Therefore, an identical balloon filled with hydrogen gas will take 3 hours to decrease its volume by 50%.

[tex]Al_2(SO_4)_3\rightarrow 2Al^{3+}+3SO_4^{2-}[/tex]
, i= 5 as it is a electrolyte and dissociate to give 5 ions. and concentration of ions will be [tex]2\times 0.1+3\times 0.1=0.5[/tex]
2. For 0.10 mol sucrose
, i= 1 as it is a non electrolyte and does not dissociate, concentration of ions will be [tex]1\times 0.1=0.1[/tex]
3. For 0.40 mol glucose
, i= 1 as it is a non electrolyte and does not dissociate, concentration of ions will be [tex]1\times 0.4=0.4[/tex]
4. For 0.2 [tex]NaCl[/tex]
[tex]NaCl\rightarrow Na^{+}+Cl^{-}[/tex]
, i= 2 as it is a electrolyte and dissociate to give 2 ions, concentration of ions will be [tex]1\times 0.2+1\times 0.2=0.4[/tex]
Thus as concentration of solute is highest for [tex]Al_2(SO_4)_3[/tex] , the vapor pressure will be lowest.

Explanation:
Rank the following elements by electron affinity 1) fluorine 2) selenium 3) arsenic 4) potassum 5) argon
Answer:
Fluorine > Selenium > Arsenic > Potassium > Argon
Explanation:
Electron affinity describes the ability or readiness or tendency of an atom to gain an electron.
The higher the value, the higher the tendency. Electron affinity depends on the on the nuclear charge and atomic radius. When nuclear charge is more, electron affinity is high, when atomic radius increases electron affinity reduces.
Noble gases such as Helium, Neon, and Argon would have 0 affinity for electrons because of their stable electronic configuration. From the list, Ar is the least in terms of electron affinity.
Potassium is a metal with large electropositivity which describes the tendency of an atom to lose electrons. Potassium would readily lose electrons instead of gaining.
Between Arsenic and Selenium: Arsenic belongs to group V and Selenium group VI. The two elements both belong to period IV on the periodic table. Across a period, electron affinity increases due to increase in nuclear charge. Therefore, Selenium would have a greater electron affinity compared to Arsenic.
Fluorine has the highest electron affinity of all. It needs just an electron to complete its octet.
The ordering from highest to lowest electron affinity among Fluorine, Selenium, Arsenic, Potassium, and Argon is likely Fluorine > Selenium > Arsenic > Argon > Potassium. This ranking considers each element's tendency and willingness to accept an additional electron to form a negative ion.
Explanation:The question asks to rank Fluorine, Selenium, Arsenic, Potassium, and Argon by electron affinity. Electron affinity refers to how readily an atom accepts an additional electron to form a negatively charged ion, with a more negative EA value indicating greater attraction for the incoming electron.
Starting with Fluorine, with an electron affinity (EA) of -322 kJ/mol, which has a high electron affinity due to its atomic number (nine) and seven electrons in its valence shell, making it highly likely to bond with other atoms. However, its small valence shell size (n = 2) causes significant repulsion with other electrons already present.
Next is Argon, a noble gas that generally exhibits low electron affinities due to fully-filled valence orbitals, meaning they don't tend to attract additional electrons. Potassium and other alkali metals traditionally have very low (positive or close to zero) electron affinities since they prefer to lose an electron to achieve a stable electron configuration.
Lastly, nonmetals like Selenium and Arsenic, usually have higher electron affinities since they're more likely to gain an electron to complete their valence shells. Based on the trends in the periodic table, the rank from highest electron affinity to lowest would most likely be: Fluorine > Selenium > Arsenic > Argon > Potassium.

What is added to white sugar to create brown sugar?
Brown sugar is made by adding molasses to refined white sugar, which may have been processed using bone char. The addition of molasses gives the distinct color and flavor to brown sugar.
Brown sugar is created by adding molasses to refined white sugar. This addition not only gives brown sugar its distinct color, but also imparts a rich flavor and increases the moisture content compared to white sugar. In the production process of brown sugar, it is important to note that if the white sugar utilized has been refined using bone char as a decolorizing filter, then the same process would likely be used in the production of the brown sugar from that manufacturer.
Bone char is derived from animal bones, and even though it is widely used in the sugar industry to achieve the white color of sugar, some consumers may seek alternatives due to dietary preferences or ethical concerns.
Sugar comes in various forms including beet sugar, cane sugar, and specialty sugars like coconut sugar or maple sugar. As for icing or powdered sugar, often used in icings and baked goods, it consists of refined sugar mixed with cornstarch and might also involve the use of bone char in its production.

In this problem, assume that all fission reactions are of this kind. In fact, many different fission reactions go on inside a reactor, but all have similar reaction energies, so it is reasonable to calculate with just one. The products of this reaction are unstable and decay shortly after fission, releasing more energy. In this problem, you will ignore the extra energy contributed by these secondary decays.

How can you determine through observation that a mixture is a suspension
Answer:
You can determine through observation that a mixture is a suspension from the fact that particles separate and a solid substance is formed at the bottom of the mixture.Explanation:
Suspensions are heterogenous mixtures where particles settle when times passes.
The partilces in suspensions are not dissolved (solvated by a solvent). The mixtures where the particles are dissolved are solutions. Then, solutions and supensions are different in that the former have the particles solvated and the latter not.
The particles in a solution are molecules or ions. Such solvated particles in a solution are very small; in comparison,the particles on a suspension are larger. Then, the weight of the particles in a suspension makes that they separate from the liquid and settle down.
Final answer:
A mixture is a suspension if it has a cloudy appearance and the particles settle out over time, a process known as sedimentation. Unlike solutions, suspensions are heterogeneous and the suspended particles are often visible and can be filtered out.
Explanation:
To determine if a mixture is a suspension, you could look for a few key characteristics. Suspensions are heterogeneous mixtures which means they are composed of different substances that remain separate upon standing. One clear indication that a mixture is a suspension is that you will notice the suspended particles settling out of the mixture over time. This process is known as sedimentation. Suspensions also appear cloudy due to the presence of large particles that are often visible to the eye or can be seen with a magnifying glass.
By contrast, a solution is a homogeneous mixture where the dissolved species do not settle out but remain evenly distributed. A common example of a suspension that can be observed in everyday life is muddy water. When left undisturbed, the mud particles, which are suspended in the water, will settle to the bottom, leaving clearer water above the sediment. Similarly, in mixtures like flour and water, after mixing and then allowing it to stand, the flour will gradually settle to the bottom of the container.
It's important to note that mixtures like milk of magnesia are also suspensions. Instructions often require shaking of the container before use to ensure that the settled particles are evenly redistributed throughout the liquid.
To sum up, the consequential settling of particles and the cloudy appearance are definitive indicators that a mixture is a suspension and not a solution or colloid.

Alkali metals react with water to produces what product?
Answer:
Alkali metals react with water to produce hydroxide and hydrogen gas.Explanation:
That is a chemical property of alkali metals: they are highly reactive and react vigorously with water to produce the correspondant hydroxide and hydrogen gas.
These are some of those reactions:
2Li (s) + 2H₂O (l) → 2LiOH (aq) + H₂(g) ↑2Na (s) + 2H₂O (l) → 2NaOH (aq) + H₂(g) ↑2K (s) + 2H₂O (l) → 2KOH (aq) + H₂(g) ↑The alkali metals are the elements of group 1 of the periodic table: Li, Na, K, Rb, Cs, and Fr. They have one valence electron which may lose easily to form an ion with charge +1.
Alkali metals react with water to produce hydrogen gas and a basic solution of the metal hydroxide (for instance, sodium hydroxide when lithium is in the reaction). This reaction signifies the easier oxidation of alkali metals compared to hydrogen.
Explanation:When alkali metals react with water, they form hydrogen gas and a basic solution of the metal hydroxide. This vigorous reaction reveals that alkali metals are easier to oxidize than is hydrogen. For instance, considering the reaction of lithium with water:
2Li(s) + 2H₂O(l) --> 2NaOH(aq) + H₂(g)
The solid state (s) lithium reacts with liquid water to generate hydrogen gas and the ionic compound sodium hydroxide. This sodium hydroxide, which is a solid in its pure form, promptly dissolves in water.
The same kind of reaction occurs with other alkali metals and also some alkaline earth metals, although beryllium and magnesium are exceptions.

What can acid rain do to buildings and statues
Answer:
Corrosion and dissolution
Explanation:
Acid rain typically can corrode metallic parts of buildings thereby weakening them. Acids can generally affect most compounds in which metals are no exceptions. We find corrugated roofing sheets becoming weaker and less durable as the rain persists. This is due to the acidity of the rain in such an environment.
Acids reacts vigorously with limestone. Limestone can be used in construction works and it is one of the key component of cements. In contact with acid rain, cemented plasters on buildings can be dissolved and rendered weak.
Marble is a metamorphic limestone. It is rich in calcium carbonate. Due to its beautiful nature, it is used in building statues and for a host of stone works. Acid rain can dissolve statues and also make them weak. This reaction defaces them.
