If a sample of 2 moles of nitric oxide gas was reacted with excess oxygen, how many moles of nitrogen dioxide would be produced?

If a sample of 2 moles of nitric oxide gas was reacted with excess oxygen, 2 moles of nitrogen dioxide would be produced.

Explanation:

The balanced reaction is:

2 NO + O₂ → 2 NO₂

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
