Question

v) A metallic oxide which can be reduced into metal by hydrogen.​

Answer 1

Answer:

No

Explanation:

Aluminium oxide cannot be reduced by hydrogen.

Answer 2

A metallic oxide which can be reduced into metal by hydrogen is lead oxide (PbO).

• There are various metal oxides which can react with the hydrogen gas in order to form various products.

• But,only a few metal oxides can react with hydrogen to get reduced into the constituent metal element.

• Similarly,the lead oxide is a metal oxide which can be reduced into the lead while reacting with the hydrogen gas.

• Chemical equation :

PbO + H2 = Pb + H2O

(Here,the oxygen is detached from the lead oxide and that's why the lead oxide is reduced.)
