Answer 1

Answer:

i) When lead(II) nitrate is heated, it decomposes into lead (II) oxide, nitrogen dioxide and oxygen.

ii)When silver nitrate solution is added to sodium chloride solution, then a white precipitate of silver chloride is formed alongwith sodium nitrate solution.

iii)Silver Nitrate is very sensitive to light. This means, that the chemical will react when exposed to light. So, when this is left exposed to sunlight or any bright light, it will start to hydrolyze. This will result in the formation of black or brown colored silver oxide and nitric acid.

iv) When magnesium ribbon is burnt in air, it combines with oxygen to form white powder magnesium oxide MgO with the release of heat and light.

v)When a piece of Sodium is dropped into water then it will form Sodium hydroxide and releases hydrogen gas.
