So, there's this really cute guy. He laughs a moderate amount around me, and I think we click really well. He teaches me when I need teaching, and he makes me laugh.

As the temperature of a gas decreases, what change occurs in the amount of kinetic energy?

Answers

Solid particles have the least amount of energy, and gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles. A change in phase may occur when the energy of the particles is changed.

which contributes to acid rain? A. burning fossil fuels B. nuclear power C. solar power D. hydroelectric power

Answers

The answer is (A) burning fossils fuels releases excess amounts of CO2 ( Carbon dioxide) which reacts with H2O in the atmosphere.
CO2 + H2O -> H2CO3

H2CO3 is known as carbonic acid.
Carbonic acid contributes to problems such as ocean acidification and can dissolve limestone ( CaCO3) sculptures.
Shown by this reaction H2CO3 + CaCO3 -> Ca(HCO3)2 producing Calcium Hydrogen Carbonate.

There are also different causes of acid rain such as Sulfur Dioxide (SO2) and Nitrogen Oxide (NO) which can cause respiratory problems.

What is true about the energy involved in a chemical reaction?

Answers

The energy needed for a chemical reaction is called the activation energy. This energy is to be present in order for the reaction to happen. This can be achieved by supplying or releasing heat from a system of reactants. This can achieved faster by using a catalyst.

Help!! How many moles of CaCO3 are needed to get 2.35 moles of CaO? What would be my reasoning and evidence?

Answers

Equation

CaCO3 ===> CaO + O2

Solution

If you start with this equation, then the balance numbers (molar ratios) are

1 for the CaCO3
1 for the CaO
1 for the O2

If you want 2.35 moles of CaO then you are going to have to start out with 2.35 moles of CaCO3

Final answer:

In the decomposition of calcium carbonate to form calcium oxide, there is a 1:1 mole ratio. Therefore, to get 2.35 moles of calcium oxide, 2.35 moles of calcium carbonate are required.

Explanation:

To answer this question, you need to consider stoichiometry, which is the study of the relationships or ratios between the amounts of products and reactants in chemical reactions. The balanced chemical equation for the thermal decomposition of calcium carbonate (CaCO3) to form calcium oxide (CaO) and carbon dioxide (CO2) is:

CaCO3(s) → CaO(s) + CO2(g)

This equation tells us that 1 mole of CaCO3 will produce 1 mole of CaO. Therefore, if we need 2.35 moles of CaO, we would need 2.35 moles of CaCO3 because of the 1:1 mole ratio in the chemical reaction.
