Question

Identify the substances that are oxidised and the substances
that are reduced in the following reactions.
4Na(s) + 0.0 - 2Na Ols)
(11) CuO(s) + H lg - Cu(s) + H OM​

Answer 1

Explanation:

In this equation:

2Na(s) + 02 -> 2Na Ols)

Na is oxidised.

In this equation:

CuO(s) + H2 - >Cu(s) + H2O

CuO is reduced to Cu.

H2 is oxidised to H2O.
