Lithium nitride reacts with water to form ammonia and aqueous lithium hydroxide.

a. Write and balance the chemical equation.
b. What mass of water is needed to react with 32.9 g of lithium nitride?
c. How many moles of ammonia are produced from 66 g lithium nitride?
d. Calculate the mass of lithium nitride that must be added to excess water to produce 15.0 L ammonia at STP?

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
