Using your knowledge of Stoichiometry, answer the following questions (you will need to balance chemical reaction, first).
1) ____H2O1 (l) + ____Fe (s) ---> ____Fe2O3 (s) + ____H2 (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?
Answers:
1) Coefficients for balanced equation (species as written): 3,2,1,3
1a) 0.248 moles Fe
1b) 38.4g H2O1
2) Coefficients for balanced equation (species as written): 2,2,3
2a) 2.09 moles O2
2b) 1.48 moles K1Cl1
