Question

How much of Cao will be produced by decomposition of 7.5 g of CaCo3

Answer 1

Answer:

Reaction is follows =)

CaCO3 ======> Cao + CO2

given mass of caCO3 = 7.5g

from eq We get that

I mol CaCO3 gives = Imol cao

100g CaCO3 gives = 56g

1g. " " =56/100=0.56g

7.5g. " " = 0.56X7.5=4.2 g

so , 4.2g of Cao will be produced by decomposition of 7.5 g of CaCo3 .
