Balance the following skeleton equation :
`FeSO_(2) + O rarr Fe_(2)O_(3) + SO_(2)`

In the reaction x FeS_2 + yO_2 rarr Fe_2 O_3 + SO_2

What do you mean by a balanced chemical equation ? Balance the following equations : (i) Al + Fe_(2)O_(3) to AI_(2)O_(3) +Fe (ii) Na +H_(2)O to NaOH + H_(2) (iii) Fe + O_(2) to Fe_(3)O_(4)

Balance the following chemical equations (a) FeSO_(4)overset("Heat")toFe_(2)O_(3)+SO_(2)+SO_(3) (b) Pb(NO_(3))_(2)(s) overset("Heat")toPbO(s)+NO_(2)(g)+O_(2)(g)
