Calcium metal reacts with oxygen gas in the air to form calcium oxide. Suppose we react 11.9 mol of calcium with 5.02 mol of oxygen gas. Determine the number of moles of calcium oxide produced after the reaction is complete. 2Ca(s) + O2(g) → 2CaO(s).
Added by Jessica B.
Step 1
According to the balanced chemical equation, 2 moles of calcium react with 1 mole of oxygen to produce 2 moles of calcium oxide. So, the ratio of Ca:O2:CaO is 2:1:2. We have 11.9 moles of calcium and 5.02 moles of oxygen. Show more…

A 5.025-g sample of calcium is burned in air to produce a mixture of two ionic compounds, calcium oxide and calcium nitride. Water is added to this mixture. It reacts with calcium oxide to form $4.832 \mathrm{~g}$ of calcium hydroxide. How many grams of calcium oxide are formed? How many grams of calcium nitride?
