$\huge{\boxed{\mathcal\green{♡}{\red{Answer}\green{♡}}}}$

Explanation:

Silver chloride is decomposed in presence of sunlight to give

silver and chlorine gas.

              sunlight

2AgCl(s) -------------> 2Ag (s)+Cl2(g)

b)Calcium oxide reacts with water to give lime water.

CaO (s) +H2O (l) ---> Ca(OH)2 + Q

c)Sodium hydroxide reacts with hydrochloric acid to give

sodium chloride and water.

NaOH(s) + HCl(aq) ----> NaCl(aq) +H2O(l)

d)Dil. hydrochloric acid is added to copper oxide to give green

coloured copper chloride and water.

CuO + 2HCl (dil.) → CuCl2 + H2 O

e)Solution of barium chloride and sodium sulphate in water

reacts to give insoluble barium sulphate and solution of sodium

chloride.

BaCl2(aq) + Na2SO4 -------> BaSO4↓+2NaCl(aq)
