(a)
Interpretation:
It should be identified that whether the given reaction is balanced or not. If it is an unbalanced equation the equation should be balanced.
Concept introduction:
In a balanced equation the number of atoms of each element as a reactant is equal to the number of atoms of that element as a product.
Coefficient is a number placed before a formula in a chemical equation.
A balanced equation should be obeying the law of conservation of mass. Law of conservation of mass states that, the number of atoms remains constant throughout the reaction, simply it can be stated as follows, “during a
