Using the balanced chemical reaction in CP 2nd Set of Balancing Chemical Reaction Homework, give the correct molar ratio for the following:

1) ____Al₂O_{3 (s)} ---> ____Al_(s) + ____O_{2 (g)}

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) ____Cu₁Cl_{2 (s)} + ____H₂S_{1 (aq)} --> ____H₁Cl_{1 (aq)} + ____Cu₁S_{1 (aq)}

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?
