What advantage does gasoline have over electricity for cars?

Answers

You don’t have to stop & charge so often , you can just fill up & go

Final answer:

Gasoline has a higher energy density than electricity stored in lithium-ion batteries, enabling more energy to be carried per unit of weight. Gasoline vehicles can refuel quickly, offering convenience for long-distance travel, while electric vehicles require longer recharge times. Additionally, gasoline's safety profile is relatively high given its energy content, as it burns rather than explodes.

Explanation:

One of the main advantages that gasoline has over electricity for powering cars is its higher energy density. Gasoline contains approximately 13 kWh/kg, while the energy density of lithium-ion batteries is about 0.2 kWh/kg, which is substantially lower. This means that gasoline can deliver more energy per unit of weight than batteries can, making it a more energy-dense fuel source.

An additional advantage is the rapid refueling capability of gasoline vehicles. A car can fill its tank with gasoline at a rate of 15 MW, allowing it to be ready for further travel in a matter of minutes, whereas electric cars often require hours to fully recharge. This convenience factor is a significant benefit for long-distance travel or in situations where quick refueling is necessary.

Safety is another aspect where gasoline has an advantage. Although gasoline is flammable, it is not as explosive as one might think—the vapor mix with oxygen burns rather than explodes, making it relatively safe for an energy source with such high energy content.

Explain what domain would best be represented by the "?" in the diagram.

A) Eukarya because the organisms are all eukaryotic.
B) Eukarya because the organisms are all prokaryotic.
C) Bacteria because some of the organisms are autotrophs.
D) Archaea because the organisms are all diverse bacteria.

Answers

Final answer:

The correct answer is 'Eukarya because the organisms are all eukaryotic' since the organisms mentioned have cells with nuclei. Bacteria and Archaea are both prokaryotic and do not contain organisms with eukaryotic cells.

Explanation:

The correct answer to the question is A) Eukarya because the organisms mentioned are all eukaryotic. This means that the cells of these organisms contain nuclei. The domain Eukarya includes diverse groups such as animals, plants, fungi, and protists. These kingdoms are distinguished by the presence of eukaryotic cells, which differentiate them from prokaryotic cells found in the other two domains, Bacteria and Archaea, both of which lack a nucleus. Bacteria and Archaea are known as prokaryotes and often consist of single-celled organisms. Eukarya, on the other hand, can consist of both unicellular and multicellular organisms. Therefore, Option B 'Eukarya because the organisms are all prokaryotic' is incorrect as eukaryotes have a nucleus. Option C 'Bacteria because some of the organisms are autotrophs' is not correct either since autotrophy is not exclusive to Bacteria and does not define domain classification on its own. Lastly, Option D 'Archaea because the organisms are all diverse bacteria' is incorrect because Archaea is a separate domain, and it encompasses organisms that are genetically distinct from bacteria and eukaryotes, despite their prokaryotic cell structure.

what is the total number of moles of solute in 2230 ml of 3.0 M NaOH solution.

Answers

The total number of moles of solute in 2230 mL of a 3.0 M NaOH solution is calculated by converting the volume to liters and multiplying by the molarity, resulting in 6.69 moles of NaOH.

The total number of moles of solute in 2230 mL of 3.0 M NaOH solution can be calculated by using the definition of molarity, which is the number of moles of solute per liter of solution. The following steps are used for the calculation:

Convert the volume from milliliters (mL) to liters (L), knowing that 1 L = 1000 mL.Multiply the volume in liters by the molarity (M) to find the total moles of solute.

First, convert 2230 mL to liters: 2230 mL
1000 mL/L = 2.23 L.

Next, multiply the volume by the molarity: 2.23 L × 3.0 M = 6.69 moles of NaOH.

Therefore, the correct answer is that there are 6.69 moles of NaOH in 2230 mL of a 3.0 M NaOH solution.

What are diseases?

Diseases are defined as a specific aberrant condition that adversely affects an organism's structure or function on the whole or in part but is not immediately caused by an external harm. The onset of chronic diseases may be delayed by eating healthfully, exercising regularly, and abstaining from cigarettes and excessive alcohol use, among other factors.

Bacteria are defined as the creatures without a proper nucleus and only a few organelles that are prokaryotic unicellular organisms. The bacteria in our bodies help our bodies digest food, help us access nutrients, and neutralize poisons. Three distinguishing characteristics of bacteria are: 1) their lack of membrane-bound organelles, 2) their unicellularity, and 3) their small size.

How many liters of 1.20 M calcium nitrate are required to produce .1 moles of calcium sulfate? Please balance the equation before solving the problem.

Answers

Answer:

0.083L

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

Ca(NO3)2 + H2SO4 —> CaSO4 + 2HNO3

Next, we shall determine the number of mole of Ca(NO3)2 needed to produce 0.1 mole of CaSO4.

From the balanced equation above,

1 mole of Ca(NO3)2 reacted to produce 1 mole of CaSO4.

Therefore, 0.1 mole of Ca(NO3)2 will also react to produce 0.1 mole of CaSO4.

Finally, we can determine the volume of Ca(NO3)2 needed for the reaction as follow:

Mole of Ca(NO3)2 = 0.1 mole

Molarity of Ca(NO3)2 = 1.20M

Volume =?

Molarity = mole /Volume

Volume = mole /Molarity

Volume = 0.1/1.2

Volume = 0.083L

Therefore, 0.083L of Ca(NO3)2 is needed for the reaction.

144g

Answers

Answer: 72 g of [tex]H_2O[/tex] is formed.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} O_2=\frac{64}{32}=2moles[/tex]

[tex]2H_2+O_2(g)\rightarrow 2H_2O[/tex]

Choose the correct energy transformation for the burning of a piece of wood. A. heat energy to light energy B. light energy to heat energy C. chemical potential energy to heat energy D. heat energy to chemical potential energy

Answers

Answer:

C

Explanation:

In the case of burning wood, stored potential energy in the wood is released due to heating by other excited atoms.

Final answer:

The burning of wood transforms chemical potential energy stored in the wood into heat energy, making option C the correct answer.

Explanation:

The correct energy transformation for the burning of a piece of wood is chemical potential energy to heat energy. This process is an example of a chemical reaction where the chemical energy stored in wood's molecules is released as heat and light energy when the wood combusts.

The chemical potential energy stored in the bonds of the wood is released as heat and light during the combustion process. This chemical potential energy is converted into heat energy, which is evident through the warmth generated by the burning wood. Additionally, some of this energy may also be transformed into light, but the primary conversion is from chemical potential energy to heat.

A 100g sample of Carbon-14 has a half-life of 5 years. How much Carbon-14 is left after 10 years?

Carlos stomps a soda con flat and throw it away. Which of the following statements BEST describes the change made in the soda can?
The soda can kept the same mass as it changed in shape only
The soda can lost mass as it was changed into a smaller size
The soda con gained more moss because its shape changed
The soda can lost mass as it was crumpled and changed form

Answers

Answer:

The soda can kept the same mass as it changed in shape only

Explanation:

Law of Conservation states "mass cannot be created or destroyed" therefore this is why the mass hasn't changed, but when it was smashed the shape changed.

Final answer:

The soda can's mass remains the same after being stomped and flattened, as no matter is added or removed during this physical change, which is explained by the Law of Conservation of Mass.

Explanation:

The statement that best describes the change made in the soda can after Carlos stomps on it is that the soda can kept the same mass as it changed in shape only. This is explained by the Law of Conservation of Mass, which states that the mass of a closed system of substances will remain constant, regardless of the processes acting inside the system. Therefore, even though Carlos changed the can's shape by stomping on it, he did not add or remove matter from the can, so its mass remained unchanged. This principle is crucial in chemistry and holds true for both physical changes, like changing the shape of a can, and chemical changes, where substances may change form but the total mass remains constant.

How many moles of gas are contained in 890.0 mL at 21.0 °C and 750.0 mm Hg pressure?

Answers

Answer:

(0.9868 atm)(0.89 L) = (x)(0.0821 L-atm)(294 K)

0.87825 = (x) 24.1374

x = 0.03638 moles :)

Explanation:

Given the value of the temperature and the pressure, the amount of the ideal gas contained in the given volume is 0.036mol.

Ideal Gas Law

The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.

It is expressed as;

PV = nRT

Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )

Given the data in the question;

Volume of gas V = 890.0 mL = 0.89LTemperature T = 21.0°C = 294.15KPressure P = 750.0mmHg = 0.986842atmAmount of gas n = ?

To determine the amount of  gas, we substitute our values into the expression above.

PV = nRT

n = PV / RT

n = ( 0.986842atm × 0.89L ) / ( 0.08206 Latm/molK × 294.15K )

n = 0.87828938Latm / 24.137949Latm/mol

n = 0.036mol

Therefore, given the value of the temperature and the pressure, the amount of the ideal gas contained in the given volume is 0.036mol.
