Answer 3

Calcium nitrate + carbon dioxide + water

Ca(NO3)2 +CO2 + H2O

Question 4

The reaction of sulphuric acid and calcium carbonate

H2SO4 + CaCO3

Answer 4

Calcium sulphate + carbon dioxide + water

CaSO4 + CO2 + H2O

Question 5

Calcium oxide + water

CaO + H2O

Answer 5

Calcium hydroxide- limewater

Ca(OH)2

Question 6

Calcium Hydroxide + Carbon dioxide- first and second change

Ca(OH)2 +CO2

Answer 6

1) Calcium carbonate + water

(Cloudy limewater)

CaCO3 + H2O

2) Calcium carbonate + water + carbon dioxide

(Colourless limewater- Calcium hydrogen carbonate dissolved back into the acid)

CaCO3 + H2O + CO2
