Try it on paper first. A hint, the key idea and the worked solution are here when you need them.
A lime kiln heats limestone: . From of calcium carbonate, of quicklime is collected. Find the theoretical mass of quicklime and the percent yield. Use and CaO g/mol.
Rounds of the equation for a reactant . The smallest is the extent, and its reactant is limiting. Products: extent coefficient. Excess left: moles extent coefficient. Percent yield . At STP a mole of gas fills .
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. Moles. mol of carbonate.
Step 2. Theoretical mass. g of CaO.
Step 3. Yield. .
Answer: g in theory, a yield of .
