The smell of hot food moves faster than the smell of cold food. Which property of gas is responsible for this?
miskamm [114]
When pressure is added to a gas the molecules bounce around really fast and push against the walls of its container. That's why when you squeeze an empty water bottle you can crush it all the way. The smaller the container the more the molecules hit the walls faster and that's what creates pressure. While moving around the molecules get hot as they speed up. Heat = Pressure.

Choose all of the following mole ratios that are correct for the reaction given below. Be sure to choose all that apply.
Dennis_Churaev [7]

Answer:

2 moles NH3 = 1 mole of N2

3 moles of H2 = 1 mole of N2

3 moles of H2 = 2 moles of NH3

Explanation:

The balanced equation for the reaction is given below:

N2 + 3H2 —> 2NH3

From the balanced equation above,

1 mole of N2 reacted with 3 moles of H2 to produce 2 moles of NH3.

Thus, we can say that:

1 mole of N2 = 3 moles of H2

1 mole of N2 = 2 moles of NH3

3 moles of H2 = 2 moles of NH3

Thus, considering the options given above, the right answers to the question are:

2 moles NH3 = 1 mole of N2

3 moles of H2 = 1 mole of N2

3 moles of H2 = 2 moles of NH3
