Answer to Question #278889 in General Chemistry for elyse

Question

Nitrogen oxide is a pollutant commonly found in smokestack emissions. One way to remove it is to react it with ammonia. (a)Write the balanced equation for this reaction and (b) calculate how many liters of ammonia are required to change 12.8 L of nitrogen oxide to nitrogen gas? Assume 100% yield and that all gases are measured at the same temperature and pressure (STP).

Answer 1

4NH3 + 6NO → 5N2 + 6H2O

b)

Molar mass of NO=30.01

12800/30.01=426.52moles

Molar mass of NH3=17.031

17.031×426.52×4/6

=4,842.71

= 4.84271L
