Answer the following:

a. Calculate the quantity of moles of NH3 gas that form when 4.20 mol of N2H4 liquid completely reacts: 3 N2H4(I)-----> 4NH3(g) + N2(g)

b. Calculate the theoretical yield in grams AlI₃ from the complete reaction of 18.3 grams Al, aluminum iodide, according to the following balanced chemical equation: 

2 Al(s) + 3 I₂(s) → 2 AlI₃(s)

c.  Determine the mass in grams of C₄H₁₀ that are required to completely react to produce 8.70 mol of CO2 according to the following combustion reaction:

2 C₄H₁₀(g) + 13 O₂(g) → 8 CO₂(g) + 10 H₂O(g)

d.  Determine the quantity of molecules of Cr₂O₃ that form when 1.34 × 10³ g of oxygen completely reacts according to the following equation:

4 Cr(s) + 3 O₂(g) → 2 Cr₂O₃(s)
