Question

We should balance a skeletal equation.... justify

Answer 1

Answer:

A chemical equation is to balanced so that it follows the law of conservation of mass . Balanced chemical equations is occur when atoms of the different elements in the reactant side is equal to the atoms of the element in the product side ... Balancing the chemical equations is a process of trial and error.

Answer 2

Answer:

Yes, we must balance a skeletal equation. This is necessary so as to follow the law of conservation of mass. According to the law of conservation of mass, mass can neither be created nor be destroyed during a chemical reaction. Fundamentally, the mass of reactants is always equal to that of products. Thus, there is a need to balance such eq.ⁿ

For Example,

Mg+O₂→MgO(skeletal)

2Mg+O₂→2MgO(balanced)
