Answer:

The mass of oxygen that participates is 2.72g

Explanation:

Oxygen gas is O2.

O2 has the molar mass of approximately 32.

Mass can be calculated by multiplying the molar mass and the moles.

Moles = Mass/Molar mass

therefore, Mass= Moles*Molar mass

Which is equal to 32*0.085= 2.72g

Answer:

B) high temperatures increase the activation energy of a reaction.

Explanation:

Ammonia is formed when the nitrogen gas is combined with hydrogen gas in a very high temperature. The high temperature increases the activation energy and nitrogen atom make chemical bonds with hydrogen atom results in the production of ammonia. At room temperature, they cannot react with each other.
