<span>Equal amounts (moles of nitrogen and oxygen).
a. which gas has the higher partial pressure?
Partial pressure is proportional to the molar fraction of the gas.
Given that there are equal amounts, the molar fractions and the partial pressures are equal.
b. molecules of which gas have the higher average velocity?
The average velocity is inversely related to the square root of molar mass of the gas, then the gass with the lower molar mass will have the higher average velocity.
Molar mass of N2 = 2 * 14 g/mol = 28 g/mol
Molar mass of O2 = 2 * 16 g/mol = 32 g/mol
Then, N2 will have a higher average velocity.
c. the molecules of which gas effuses more quickly if a small hole was opened in the flask?
The effusion rate is inversely related to the square root of the molar mass, then the gas with the lower molar mass will effuse more quickly.
Therefore, N2 will effuse more quickly.

Answer:
Exothermic, it obeys the law of conservation of energy
Explanation:
The reaction is an exothermic change. In this kind of change, heat is liberated to the surrounding. So the surrounding becomes hotter at the end of the heat change.
In chemical reactions that involves the loss of energy as heat, they obey the law of conservation of energy.
The law of conservation of energy states that energy is neither created nor destroyed but transformed from one form to another. In such reactions as this, chemical energy is transformed into heat energy.
