Need some help on my study guide for my AP Chemistry??? Please help ASAP! 

Ethanol (C2H5OH) is burned in the presence of oxygen gas to produce carbon dioxide and water (ΔH = 1234.7kJ). 

How much heat is produced when 9.75g of Oxygen and 15.5g of Ethanol react? 

What is the limiting reactant? 

How many grams of oxygen do you need go fully react all 15.5g of ethanol? 

If 7.50g of ethanol react how much water is produced (in moles)? 

If 7.50g of ethanol react how much carbon dioxide is produced? 

If 2.25g of carbon dioxide is produced from 7.50g of ethanol, what is the percent yield?

Hydrogen gas reacts with Oxygen to form water (ΔH = -571.6kJ). How much heat is released when 45g of water are produced? 

How much hydrogen gas in grams do you need to produce 750g of product? 

If you have 10g of hydrogen gas and 10g of oxygen gas how much water can you produce? 

What is the limiting reactant? 

What is the percent yield if 2.25g of water is produced? 

How much heat is produced?
