Question

What weight of calcium oxide will be formed on heating 19.3g of calcium carbonate?

Answer 1

Answer:

10.8

Explanation:

caco3 gives cao + co2

mass of caco3 given =19.3 gram

moles=19.3/100=.193

moles of cao= coefficient of caco3/coefficientofcao x moles of caco3

1/1 x.193

moles of cao=.193

weight=.193x56=10.808
