Methanol (CH4O) is used in the production of many chemicals. Methanol is made by reacting carbon monoxide and hydrogen at high temperature and pressure.
CO(g) + 2H2(g) ---> CH4O(g)
1) How many molecules of hydrogen are needed to produce 25.O g of CH4O?
2) How many molecules of carbon monoxide are needed to produce 25.O g of CH4O?
3) How many molecules of hydrogen are needed to produce 50.0 g of CH4O?
Zinc and Nitric acid react to form zinc nitrate, ammonium nitrate, and water.
4Zn(s) + 10HNO3(aq) ---> 4Zn(NO3)2(aq) + NH4NO3(aq) + 3H2O(l)
4) How many atoms of zinc react with 1.49 g HNO3?
5) Calculate the number of molecules of zinc that must react with an excess of HNO3 to form 29.1g NH4NO3.
