(b) silver chloride is exposed to sunlight
(c) water is added to quick lime
(d) zinc is added to sodium hydroxide solution.​

Answer 1

Answer:

(a) lead nitrate crystals on strong heating decompose to form lead mono oxide , nitrogen dioxide and oxygen gas.

(b) silver chloride when exposed toh light , it decomposes to form silver metal and chlorine Gas.The reaction is used in black and white photography.

(c) when water is added to quick lime,it forms slaked lime along with the evolution of heat.

(d) Zinc reacts with sodium hydroxide solution (aq.) to form sodium zincate and hydrogen gas.

Answer 2

Answer:

(a) When lead nitrate is heated it decomposes to form lead oxide, nitrogen dioxide and oxygen.

(b) When silver chloride is exposed to sunlight, it decomposes to form silver metal and chlorine gas.

(c) When water is added to quick lime, a large amount of heat energy is evolved along with calcium hydroxide.

(d) When Zinc is added to sodium hydroxide, it forms sodium zincate along with hydrogen gas.
