(a) Lime water turns milky on passing carbon dioxide gas into it.
(b) Bubbles are produced when acetic acid is added to a solution of sodium hydrogen carbonate.

Solution

(a) When carbon dioxide $(C O_{2})$ reacts with lime water $(C a (O H)_{2})$ , then calcium carbonate $(C a C O_{3})$ and water $(H_{2} O)$ is formed.
$C a (O H)_{2} + C O_{2} ⟶ C a C O_{3} + H_{2} O$

(b) When baking soda $(N a H C O_{3})$ is added to acetic acid $(C H_{3} C O O H)$ then carbon dioxide $(C O_{2})$ gas is formed which causes appearance of bubbles.
$C H_{3} C O O H + N a H C O_{3} ⟶ C O_{2} + other substances$
