Methanol is used in the production of many chemicals. Methanol is made by reacting carbon monoxide and hydrogen at high temperature and pressure. CO + 2H2 → CH3OH

A. Calculate the number of grams of carbon monoxide needed to produce 4 moles of CH3OH.

B. How many moles of hydrogen are necessary to react with 2.85 moles CO.

The reaction of fluorine with ammonia produces dinitrogen tetrafluoride and hydrogen fluoride.
5F2 + 2 NH3 → N2F4 + 6HF

A. If you have 66.6 grams of ammonia, how many Liters of F2 are required?

4Zn + 10HNO3 → 4Zn(NO3)2 + NH4NO3 + 3H2OA. A. How many atoms of Zn react with 1.49 mole of HNO3?
B. How many molecules of Zn react with 56 grams of HNO3?
