Question

In equations given below identify the substances
which are oxidised or reduced and support
your answers with a reason.
(i)S + O2 → SO2
(ii)C + H2O → CO + H2
(iii)Fe3 + e → Fe2

Answer 1

Answer:

1) S is oxidised because of its oxidation number changed from 0 to +4

Explanation:

2) C is oxidised because of its oxidation number changed from 0 to +2 and H2 is reduced because of its oxidation number changed from +2 to 0

3) Fe2 is reduced because it gain electron
