Please help me understand how to do this?!\

1. How many molecules of Hydrogen can be liberated from the reaction of 23.7 moles of Hydrochloric acid with excess Zinc to produce zinc chloride?
HCl+Zn----->ZnCl2+H2

2. Using the equation above, how many moles of Hydrogen can be produced from 35.3 grams of Hydrochloric acid?

3. When 52 moles of benzene (C6H6) combine with oxygen, how many moles of carbon dioxide are produced? What else is produced in addition to the carbon dioxide?

4. Given a reaction in which silver nitrate reacts with aluminum chloride to produce silver chloride and aluminum nitrate, calculate the mass of silver chloride that can be prepared from 160 grams of aluminum chloride.

5. When ammonia is produced from a reaction of nitrogen and hydrogen, how many mg of ammonia can be formed from 37 moles of nitrogen?

6. If 109 moles of hydrogen are available and 57 moles of nitrogen are available in the reaction in #5 to form ammonia, which is the limiting reagent? Prove your answer with stoichiometric calculations.


PLEASE don't just give answers, please specify the methods you used.
THANKS SO SO MUCH.
