If you only have 13.7 g of aluminum metal and an excess of oxygen, what is the theoretical yield of aluminum oxide (Al2O3) in grams?

If the reaction yield is 94.4%, what mass in grams of hydrogen is produced by the reaction of 4.73 g of magnesium with 1.83 g of water? The balanced chemical equation is: Mg (s) + 2 H2O (l) → Mg(OH)2 (s) + H2 (g).

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)

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?

Propane, C3H8, a fuel used in many outdoor grills, burns in oxygen to produce carbon dioxide gas, CO2, and water vapor, H2O, as shown in the reaction below. If 2.0 mol of propane are burned (reacted with oxygen), how many moles of carbon dioxide will be produced?

Stoichiometric amounts of nitrogen gas and hydrogen gas react in a calorimeter to produce 5 g of ammonia gas. The calorimeter temperature rises 0.42 °C. The calorimeter and water have a combined heat capacity of 32.16 kJ/°C. Calculate the heat of formation of ammonia (in kJ/mol).

The common fertilizer NH4NO3(s) can explosively decompose according to the following reaction: 2 NH4NO3(s) → 2 N2(g) + O2(g) + 4 H2O(g). ΔH = -236.15 kJ/mol. What is the heat released when 80.06 g of NH4NO3(s) explodes? Molar mass of NH4NO3(s) = 80.06 g/mol.
