Answer:
Electronegativity difference of C and C:
0.0
covalent
Electronegativity difference of Mg and Cl:
1.8
ionic
Explanation:
When the difference in electronegativity is less than 1.5, elements generally form covalent bonds.
Explanation:Electronegativity is a measure of an atom's ability to attract and hold electrons in a covalent bond. When the difference in electronegativity between two elements is less than 1.5, they generally form a covalent bond.
For the pair of elements C and C, both have the same electronegativity value of 2.5, so the electronegativity difference is 0. Since the difference is less than 1.5, C and C form a covalent bond.
For the pair of elements Mg and Cl, their electronegativity values are 1.2 and 3.0 respectively. The electronegativity difference is 1.8, which is greater than 1.5. Therefore, Mg and Cl form an ionic bond.

Why did the beaker most likely feel warm
A sample of O2 occupies 75L at standard temperature and pressure. If the volume of the sample doubles, what is the new pressure of O2? _____ atm
Answer:
0.5
Explanation:
The concept Boyle's law is used here to determine the new pressure of oxygen. There are several gas laws in order to explain the properties of a gas. Boyle's law is one among them. Here the new pressure is 0.5 atm.
What is Boyle's law?Boyle's law states that at constant temperature, the volume of a given mass of gas is inversely proportional to the pressure. At constant temperature, the product of pressure and volume of a given mass of gas is constant.
Mathematically the law can be expressed as:
V ∝ 1 /P
Or PV = k (Constant)
For two gases, the equation is:
P₁V₁ = P₂V₂
Here standard pressure is 1 atm and when the volume doubles, it becomes 150.
P₂ = P₁V₁ / V₂
1 × 75 / 150 = 0.5
Thus the new pressure is 0.5 atm.

b) 2.94 g.
c) 0.02798 mol.
d) 2.06 g.
e) 0.1144 mol.
f) 4.0 mol/mol.
g) Yes, the experiment results corroborate with the formula BeSO₄.4H₂O.
Explanation:
a) Determine the mass of the original hydrate.
The mass of the original hydrated salt = The mass of the crucible with the hydrated salt - the mass of the empty crucible = 15.0 g - 10.0 g = 5.0 g.
b) Determine the mass of just the anhydrous salt.
The mass of the anhydrous salt = the mass of the crucible with the anhydrous salt (after heating) - the mass of the empty crucible = 12.94 g - 10.0 g = 2.94 g.
c) Calculate the number of moles of anhydrous salt using the molar mass of just BeSO₄.
The no. of moles of the anhydrous salt = mass of anhydrous salt/molar mass of BeSO₄ = (2.94 g)/(105.075 g/mol) = 0.02798 mol.
d) Determine the mass of water lost.
The mass of water lost = the mass of the crucible with the hydrated salt (before heating) - the mass of the crucible with the anhydrous salt (after heating) = 15.0 g - 12.94 g = 2.06 g.
e) Calculate the number of moles of water lost using the molar mass of water.
The no. of moles of water lost = the mass of water lost/molar mass of water = (2.06 g)/(18.0 g/mol) = 0.1144 mol.
f) Determine the smallest whole number ratio of moles of water : moles of anhydrous salt.
The smallest whole number ratio of moles of water : moles of anhydrous salt = The no. of moles of water lost/The no. of moles of the anhydrous salt = (0.1144 mol)/(0.02798 mol) = 4.089 mol/mol ≅ 4.0 mol/mol.
g) Did the experiment results corroborate with the formula BeSO₄.4H₂O?
Yes, the experiment results corroborate with the formula BeSO₄.4H₂O.
The original hydrate weighed 5 grams, while the anhydrous salt weighed 2.94 grams. There were 2.06 grams of water lost, and the molar ratio of water to the anhydrous salt was 4:1, confirming the formula for the hydrate.
Explanation:The mass of the original hydrate can be calculated by subtracting the mass of the empty crucible from the mass of the crucible containing the hydrate. This gives you 5 grams (15.00 - 10.00).
The mass of just the anhydrous salt is calculated by subtracting the mass of the empty crucible from the mass of the crucible containing the anhydrous compound, giving 2.94 grams (12.94 - 10.00).
The number of moles of anhydrous salt can be calculated by dividing the mass of the anhydrous salt by the molar mass of BeSO4. Using a molar mass of 105.07 g/mol, the number of moles of anhydrous salt is 0.028 mol.
The mass of water lost is the difference between the mass of the original hydrate and the mass of the anhydrous salt. This gives 2.06 grams of water.
The number of moles of water lost is calculated by dividing the mass of water lost by the molar mass of water. Using a molar mass of 18.015 g/mol, the number of moles of water lost is 0.114 mol.
The smallest whole number ratio of moles of water to moles of anhydrous salt can be calculated by dividing the number of moles of each by the smaller of the two numbers. This gives a ratio of 4:1, which matches the formula for the hydrate, BeSO4 • 4H2O, confirming the results.

in the morning a student puts a warm soda in a ice filled cooler.
he closes the cooler. at lunch the can of soda is colder. what happened to the total amount of energy in the cooler containing the can of soda and the ice?
basically all of the molecules in the can of soda started to stop moving due to the compression and change of temperature. the ice had frozen the molecules and which then made the can of soda nice and cold lol
The total amount of energy in the cooler remains the same. The warm soda transfers its heat energy to the ice, causing the soda to cool and the ice to melt. The cooler, soda, and water from the melted ice eventually reach a thermal equilibrium where they have the same temperature.
Explanation:In the scenario where a student puts a warm can of soda in a cooler filled with ice, the amount of thermal energy in the cooler's system changes due to the process of heat transfer. This process follows the second law of thermodynamics which stipulates that heat tends to flow from hotter objects to colder objects until they reach equilibrium.
In this case, the warmer soda will transfer its heat to the colder ice. During this process, the ice will absorb the heat without a rise in temperature until all of it has melted. This is because this absorbed energy is used to break the bonds holding the ice molecules together in a solid state, causing a phase change to liquid water.
Simultaneously, the soda can's temperature drops as it loses heat to the ice. Eventually, everything in the cooler—the soda, the melted ice water, and the air within—will reach the same temperature, marking the achievement of thermal equilibrium. Therefore, the total amount of energy in the cooler remains the same, it's just transferred (not lost or gained). The energy initially within the can of soda is transferred to the ice, and the overall rise in the cooler’s temperature represent this energy transfer.

what is the bond order .? calculate the bond order of H2.
Bond order: 1.
ExplanationHow many chemical bonds in a H₂ molecule?
There is one valence electron in each neutral H atom. Refer to a periodic table. H is one electron away from the closest noble gas: He. The H atoms need to achieve the noble gas configuration of He to be stable. For that, each H atom needs one more electron. There are two H atoms in an H₂ molecule. It will take 2 × 1 = 2 more electrons for both H atoms in each H₂ molecule to become stable.
Unlike ions, the H₂ molecule is neutral. There's no no extra electron for the H atoms. The two atoms need to share electrons with each other by forming chemical bonds. One chemical bond adds one electron to both bonding atoms. As a result, each bond will add two electrons to the molecule.
The H₂ molecule needs 2 extra electrons, which corresponds to 2 / 1 = 1 chemical bond.
What's the bond order?
[tex]\displaystyle\text{Bond Order} = \frac{\text{Number of Bonds}}{\text{Number of Bonding Sites}}[/tex].
The two H atoms in an H₂ molecule forms
one H-H chemical bond over one bonding site between the two H atoms.As a result,
[tex]\displaystyle\text{Bond Order} = \frac{\text{Number of Bonds}}{\text{Number of Bonding Sites}} = \frac{1}{1} = 1[/tex].
The bond order of H₂ is 1, calculated by subtracting the number of antibonding electrons from the number of bonding electrons (2 - 0), then dividing by 2. A bond order of 1 corresponds to a single covalent bond between the two hydrogen atoms.
Explanation:The bond order is a term in chemistry that refers to the number of chemical bonds between a pair of atoms. To calculate the bond order of H₂ (dihydrogen), we utilize molecular orbital theory. Given that the 0₁s (bonding) molecular orbital contains two electrons and the ot (antibonding) molecular orbital is empty, the calculation is straightforward. The bond order is calculated as one-half the net number of bonding electrons, which, in this case, is one-half the difference between the number of bonding and antibonding electrons:
Bond order of H₂ = ((bonding electrons) - 0 (antibonding electrons)) ÷ 2 = 2÷ 2 = 1.
This result corresponds to the single covalent bond observed between the two hydrogen atoms in a H₂ molecule, making the bond relatively strong and stable. The bond order of 1 reflects a single bond, which aligns with experimental data indicating that H₂ has a bond length appropriate for a single bond.

How to find the percent composition of CrF3?
Final answer:
To find the percent composition of CrF3, divide the mass of each element by the molar mass of CrF3 and multiply by 100.
Explanation:
To calculate the percent composition of CrF3, you need to find the mass of each element in the compound and divide it by the overall mass of the compound. In this case, CrF3 consists of one chromium (Cr) atom and three fluorine (F) atoms. The atomic mass of chromium is 51.996 grams/mole and the atomic mass of fluorine is 18.998 grams/mole. Therefore, the molar mass of CrF3 is (51.996 g/mol) + 3(18.998 g/mol) = 130.988 g/mol. To find the percent composition of each element, divide the mass of each element by the molar mass of CrF3 and multiply by 100. The percent composition of Cr in CrF3 is (51.996 g/mol / 130.988 g/mol) * 100 = 39.6% and the percent composition of F in CrF3 is (3(18.998 g/mol) / 130.988 g/mol) * 100 = 54.4%.

why is an energy pyramid shaped like a triangle with the point on the top?
The energy decreases as you move through the trophic levels from the bottom to the top of the energy pyramid. This is because the energy is used up by the organisms at each level. The pyramid shape is used to represent the flow of energy because of the way that energy is used up and lost throughout the system.
Answer:
The energy pyramid is one type of graphical representation of ecological relationships that is in the shape of a pyramid. The base must have the largest amount of biomass (shown as the widest bar) so it can support the energy requirements of the organisms at higher levels. Each higher level in the pyramid gets smaller (the bars get narrower) because only about 10% of the available energy transfers to the next level. The shape of the energy pyramid shows that there is enough biomass energy contained in the primary producers at the bottom to support the predators at the top, even though energy is lost at each level.

Find the moles of each product formed when 3.40 mol C3H7OH reacts with oxygen
the balanced equation for the combustion reaction is as follows
2C₃H₇OH + 9O₂ ---> 6CO₂ + 8H₂O
we are assuming that O₂ is in excess and C₃H₇OH is the limiting reactant
therefore the amount of product formed depends on the amount of C₃H₇OH present.
we have to find the number of CO₂ and H₂O moles formed
molar ratio of C₃H₇OH to CO₂ is 2:6 simplified to 1:3
when 1 mol of C₃H₇OH reacts - 3 mol of CO₂ is formed
therefore when 3.40 mol of C₃H₇OH reacts - 3 x 3.40 = 10.2 mol of CO₂ is formed
molar ratio of C₃H₇OH to H₂O is 2:8 simplified to 1:4
when 1 mol of C₃H₇OH reacts - 4 mol of H₂O is formed
therefore when 3.40 mol of C₃H₇OH reacts - 4 x 3.40 = 13.6 mol of H₂O is formed
10.2 mol of CO₂ and 13.6 mol of H₂O is formed
You burn a 1.5 g jellybean to warm 150 g of water. The temperature of the water increases by 15 °C. Water has a specific heat of 4.184 J/g • °C. How many joules does the jellybean have? A) 94.14 J B)941.4 J C)9414 J D)14124 J
Answer:
9414.0 J.
Explanation:
The amount of heat absorbed by water through burning a 1.5 g jellybean can be calculated from the relation:Q = m.c.ΔT.
where, Q is the amount of heat absorbed by water,
m is the mass of water (m = 150.0 g),
c is the specific heat of water (c = 4.184 J/g °C),
ΔT is the temperature difference (final T - initial T) (ΔT = 15.0 °C).
∴ Q = m.c.ΔT = (150.0 g)(4.184 J/g °C)(15.0 °C) = 9414.0 J.
So, the jellybean have 9414.0 J that is releases to water.
