Question

nitric oxide, n o no, reacts with oxygen gas to form nitrogen dioxide, a dark brown gas. if 8.0 g 8.0 g of o 2 o2 is allowed to react with 20. g 20. g of n o no, what mass of the excess reagent remains after the reaction is complete? assume the oxygen gas is limiting.

Answer 1

Nitrogen dioxide, the dark brown gas, is created when nitric oxide, or "no no," mixes with oxygen gas. 8.0 g 8.0 g o o 2 o2 will react with if it is allowed to. This reaction generates 0.886 moles of NO2.

Can people produce gas?

Both swallowing air and the large intestine's microorganisms aiding in food digestion cause you to produce gas. Food that is not digested travels from the small to the large bowel. When it arrives, the bacteria begin their work by producing hydrogen, carbon dioxide, or methane, which are subsequently expelled from your body.

Briefing

This reaction's chemical equation is:

2NO(g) + O2(g) → 2NO2(g)

In this limiting reagent reaction, 2 moles of NO reacts with one mole of O2  to produce 2 mole of 2NO2

0.886 mole of NO * (2 mole of NO2/2 mole of NO) = 0.886 mole of NO2

0.503 mole of O2 * (1 mole of NO2/1 mole of O2) = 1.01 mole of NO2

Hence, NO is the limiting reagent.  

In this reaction 0.886 mole of NO2 is produced
