Answer 1

Explanation:

The attachment given is the answer.

Answer 2

Explanation:

Reduction can be considered as the removal of oxygen, the addition of hydrogen, or the gain of electrons.

Removal of oxygen:

Metal ores which are oxides are reduced to the metal - this is how iron is made from iron ore. The reducing agent is carbon monoxide.

Fe2O3 + 3CO --> 2Fe + 3CO2

Addition of hydrogen:

Aldehydes and ketones can be reduced to primary or secondary alcohols respectively using aqueous sodium borohydride. This is a source of H− ions which bring about the reduction:

CH3CHO + 2[H] --> CH3CH2OH

Copper oxide can be reduced to copper by heating it while passing hydrogen gas over it. The hydrogen gets oxidised to form water.

CuO + H2 --> Cu + H2O

Gain of electrons:

The formation of non-metal ions from the corresponding element, for example during electrolysis, is an example of this, e.g.

Cl2 + 2e− --> 2Cl−

In the same way, positive metal ions can gain electrons to be reduced to the metallic element:

Cu2+ + 2e− --> Cu
