5. The industrial production of hydroiodic acid takes place by treatment of iodine with hydrazine (N2H4):
2I2 + N2H4 → 4HI + N2
a.How many grams of I2 are needed to react with 36.7 g of N2H4
Here is a worked example of a stoichiometry problem. Just follow the steps. http://www.jiskha.com/science/chemistry/stoichiometry.html
