Question

a student thermally decomposes 24.4 g of CuCO3 and obtains 11.2 g of CuO and CO2 which is released, what is the percentage yield

Answer 1

the percentage yield of the thermally decomposing CuCO3 is 46.1%.

The percentage yield of a thermally decomposing CuCO3 is calculated using the following formula:

percentage yield = (amount of CuO obtained/amount of CuCO3 used)*100

In this case, the percentage yield is calculated as follows:

percentage_yield = (11.2g/24.4g)*100 = 46.1%

Therefore, the percentage yield of the thermally decomposing CuCO3 is 46.1%.
