(a)
Interpretation: Balanced equation should be written for the given reaction
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
Steps in balancing the information
- Step 1: Write the unbalanced equation
- Step 2: Find the coefficient to balance the equation.
- The coefficient should be reduced to the smallest whole number
