Chapter 8, Problem 2E

Nitrogen and hydrogen can react to from ammonia:

${\text{N}}_2\left(g\right)+3{\text{H}}_2\left(g\right)\to 2{\text{NH}}_3\left(g\right)$

a. Write ratios showing the relationships between moles of each of the reactants and product in the reaction.

b. How many molecules of ${\text{H}}_2$

are required completely react with two molecules of ${\text{N}}_2$

?

c. How many moles of ${\text{H}}_2$

are required to completely react with 2 mol of ${\text{N}}_2$

?
