Write the balanced chemical equations for the following reactions:
(a) Calcium hydroxide + Carbon dioxide ------> Calcium carbonate + Water(b) Aluminium + Copper chloride ------> Aluminium chloride + Copper
The bal;anced equations are given below:
(a) Calcium hydroxide + Carbon dioxide → Calcium carbonate + Water
$\ Ca( OH)_{2} \ +\ CO_{2} \ \rightarrow \ Ca( CO_{3}) +\ H_{2} O$
(b) Aluminium + Copper chloride → Aluminium chloride + Copper
$2Al\ +\ 3CuCl_{2} \ \rightarrow \ 2AlCl_{3} \ +\ 3Cu$
