Copper(II) carbonate is broken down by heating to form copper(II) oxide and carbon dioxide gas. The equation for the reaction is shown. CuCO3 → CuO + CO2 31.0g of copper(II) carbonate are heated until all of the contents of the test-tube have turned from green to black. The yield of copper(II) oxide formed is 17.5g. What is the percentage yield?

Answer:
56.50%
Explanation:
precentage yield = actual yield/predicted yield * 100
17.5/31 * 100 = 56.45 (round off to 56.50)
