1.	What is effect of heat on the following compounds? (Give equations for the reactions) (i) CaCO3 (ii) CaSO42H2O
Answer» (i) CaCO₃ \(\overset{heat}{\longrightarrow}\) CaO + CO₂ (decomposition/calcinations) (ii) 2CaSO₄.2H₂O \(\overset{heat}{\underset{strongly}{\longrightarrow}}\) (CaSO₄) (Dead buront plaster)(Plaster of paris) + 2H₂O + 3H₂O

What is effect of heat on the following compounds? (Give equations for the reactions) (i) CaCO3 (ii) CaSO42H2O

Answer»

(i) CaCO₃ \(\overset{heat}{\longrightarrow}\) CaO + CO₂ (decomposition/calcinations)

(ii) 2CaSO₄.2H₂O \(\overset{heat}{\underset{strongly}{\longrightarrow}}\) (CaSO₄) (Dead buront plaster)(Plaster of paris) + 2H₂O + 3H₂O
