Question

Balance this eq in a book :
Ca(oh2) +co2 gives caco3+h2o

Answer 1

Balance Ca(OH)2+CO2--->CaCO3+H2O

The mechanism of reaction of carbon dioxide in aqueous calcium hydroxide is a double displacement reaction. Both the right (products) and left (reactants) side of the “equation are balanced”.

Answer 2

ca=1 ca=1

o=2+2=4 o=3+1=4

H=2 H=2

c=1 c=1

equation balanced
