Question

when 45.0 grams of copper (II) carbonate are decomposed with heat, how many grams of carbon dioxide will be produced???

Answer 1

Answer #1

CuCO3(s) ----------------> CuO(s) + CO2(g)

1 mole of CuCO3 decomposes to gives 1 mole of CO2

123.5g of CuCO3 decomposes to gives 44g of CO2

45g of CuCO3 decomposes to gives = 44*45/123.5 = 16.032g of CO2 >>>>>answer

Answer 2
