Question

What is the mass of copper oxide will be obtained by heating 3 mole of CuCO3​

Answer 1

Answer:

The chemical equation for the reaction is :

CuCO2

Heat

→

CuO+CO2

63.5+12+48 63.5+16

=123.5g =79.5g

123.5 g of copper carbonate upon heating given Cu=79.5g

1.0 g of copper carbonate upon heating gives Cu=

79.5

123.5

g

∴12.35 g of copper carbonate upon heating give Cu=

79.5

123.5

×12.35 g = 7.95 g
