Question

we need to balance a skeletal chemical equation give reason to justify statement

Answer 1

we need to balance because skeleton equation do not obey law of conservation of mass so we need to balance to obey the law of conservation of mass and also make the equal amount of atom on LHS and RHS

Answer 2

We need to balance a skeletal equation as skeletal equation does not follow the law of conservation of mass whereas balanced equation does follow and it is necessary for an equation to follow the law of conservation of mass.
