Upon heating, calcium carbonate decomposes to produce calcium oxide and carbon dioxide. What is the theoretical yield of #CO_2# if 235.0 g #CaCO_3# is heated?
Approx. 100 g of carbon dioxide gas are evolved.
The molar equivalence of carbonate to carbon dioxide is therefore 1:1.

The molar mass of CaCO₃ is 100.09 g/mol. The balanced equation is:
CaCO₃ → CaO + CO₂.
Calculate moles of CaCO₃: 235.0 g / 100.09 g/mol = 2.349 moles.
Theoretical yield of CO₂: 2.349 moles × 1 mol CO₂/1 mol CaCO₃ = 2.349 moles CO₂.
Convert moles to grams: 2.349 moles × 44.01 g/mol = 103.29 g CO₂.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
