Using your knowledge of Stoichiometry, answer the following questions (you will need to balance chemical reaction, first).

1) ____H₂O_{1 (l)} + ____Fe_(s) ---> ____Fe₂O_{3 (s)} + ____H_{2 (g)}

1a) How many mole of Fe do I need to make 0.372 moles of H₂ ?

1b) How many grams of H₂O₁ will I need to make 0.712 moles of Fe₂O₃?

2) ____K₁Cl₁O₃ ---> ____K₁Cl₁ + ____O₂

2a) How many mole of O₂ do I get if I react 1.39 moles of K₁Cl₁O₃?

2b) How many moles of K₁Cl₁ do I produce if I produce 71.2g of O₂?
