Using the balanced chemical reaction in [[CP 2nd Set of Balancing Chemical Reaction Homework]],
give the correct molar ratio for the following: 
 
 
 
1)&nbsp;____Al2O3 (s) &nbsp;&nbsp;&nbsp;--->&nbsp;&nbsp;____Al(s)&nbsp;&nbsp;+ ____O2 (g)&nbsp;&nbsp; 
 
 
1a) What is the correct molar ratio if you are Given information (e.g. moles) of Al2O3 and want to KNOW information of O2? 
 
 
 
1b) What is the correct molar ratio if you are Given information (e.g. moles) of O2 and want to KNOW information of Al ? 
 
 
 
 
2)&nbsp;____Cu1Cl2 (s)&nbsp;&nbsp;+&nbsp;&nbsp;____H2S1 (aq)&nbsp;&nbsp;&nbsp;-->&nbsp;&nbsp;____H1Cl1 (aq)&nbsp;&nbsp;+&nbsp;&nbsp;____Cu1S1 (aq)&nbsp;&nbsp; 
 
 
2a) What is the correct molar ratio if you are Given information (e.g. moles) of H1Cl1 and want to KNOW information of Cu1Cl2? 
 
 
 
2b) What is the correct molar ratio if you are Given information (e.g. moles) of Cu1S1 and want to KNOW information of H1Cl1?
