Magnesium hydroxide can be made from magnesium nitride according to the following equation: Mg3N2 6H2O 3Mg(OH)2 2NH3 In a certain experiment 10.0g of magnesium nitride is allowed to react with 5.00 g of water. Calculate the final mass of ammonia, water, and magnesium nitride at the end of the reaction. (Assume 100% yield)

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.
