Answer:
b .
b .The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction.

Carbon dioxide reacts with limewater to form calcium carbonate, which precipitates out of the solution. The carbon dioxide and limewater react to produce water in addition to the calcium carbonate. ... The white milky suspension/precipitate is caused by the formation of calcium carbonate.

Answer:
a) There are 2 reactions in this process:-
* CaCO3 ---heat---> CaO + CO2 (Already balanced)
* Ca(OH)2 + CO2 ----> CaCO3 + H2O (Already balanced)
b) The reactants in this reaction are:- Calcium Carbonate. (Heat is a catalyst)
c) The lime water turns milky because of formation of Calcium Carbonate in it.
d) This is a thermal decomposition reaction.
