Concept explainers
Interpretation:
The given equations are to be completed and balanced.
Concept Introduction: A
Reactants are written in left side of chemical reaction and products are written in right side of chemical reaction
In a balanced equation, the number of atomsshould be equal on both sides of the reaction.
In the case of a nonbalanced equation, choose big number in front of each atom to do balance equation.
A chemical reaction consists of the atoms or molecules that combine with each other to give a product.
