Alot Of Stoichiometry Problems

a. How many moles of aluminum oxide are produced when 0.60 mole of Iron is produced in the following chemical reaction.
2 Al_(s) + 3 FeO_s --> 3 Fe _(s) + 1 Al₂O_{3 (s)}

b. How many moles of sulfuric acid (H₂SO₄) are needed to completely react with 15.0 moles of aluminum in the following chemical reaction.
2 Al_(s) + 3 H₂SO_{4 (aq)} --> 1 Al₂(SO₄)_{3 (aq)} + 3 H_{2 (g)}

c. How many liters of oxygen gas @STP do you need to "burn" biologically to 43.5g of glucose (C₆H₁₂O₆)?
1 C₆H₁₂O₆ + 6 O_{2 (g)} --> 6 CO_{2 (g)} + 6 H₂O_{1 (l)}

d. How many liters of NH₃ are needed to react completely with 30.0L of NO in the following chemical reaction. Assume all gases @STP.
4 NH_{3 (g)} + 6 NO_(g) --> 5 N_{2 (g)} + 6 H₂O_(g)

e. How many grams of Fe₂O₃ are formed when 16.7g of Fe reacts completely with oxygen?
4 Fe_(s) + 3 O_{2 (g)} --> 2 Fe₂O_{3 (s)}

f. How many grams of calcium oxide do I need to react to obtain 5.45E25 atoms of Hg as described by following reaction.
4 HgS_(s) + 4 CaO_(s) --> 4 Hg_(l) + 3 CaS_(s) + 1 CaSO_{4 (s)}

g. How many liters of H₂O (as a gas @STP) do I produce if I react 45.6 liters of oxygen gas (@STP) with sufficient amount of hydrogen gas?
2 H_{2 (g)} + 1 O_{2 (g)} --> 2 H₂O_(g)

h. Sodium reacts with calcium nitrate to produce sodium nitrate and calcium metal. Please give balanced complete (molecular) chemical reaction including phases. How many grams of calcium nitrate did I need to react to produce 21.8g of sodium nitrate?(Sorry this reaction actually does not occur because sodium is not higher on Activity series as calcium. BUT do the problem anyway.)
