Lithium and nitrogen react to produce lithium nitride according to the equation: 6Li + N2 → 2Li3N. How many moles of N2 are needed to react with 0.450 mol of lithium?

In a stoichiometric reaction, if the volume of the reaction vessel is 1.50 L and the rate of formation of Br2 is 0.020 mol/L·s, what amount of Br2 (in moles) is formed during the first 15.0 seconds of the reaction?

If you begin with 1.3109 g of iron(III) chloride hexahydrate (FeCl3·6H2O) and it is the limiting reactant, calculate the theoretical yield (in grams) of the product, Fe(C5H7O2)3, assuming complete reaction.

If you have 3.2 grams of Zn, how many liters of H2 gas could be produced in the following chemical reaction at STP? Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)
