The complete and balanced molecular equation is-
K₂SO₄(aq) + SrI₂(aq) → KI(aq)+ SrSO₄(s)
Both sides of the reaction must have an equal amount of atoms in each element to balance the equation.
What is a balanced chemical reaction?
- A balanced chemical reaction is one in which both the reactant and product sides of the reaction include an equal number of atoms from each of the constituent components. For the chemical equation to adhere to the Law of the conservation of mass, it must be balanced.
- An equation that has the same number of each type of atom on both sides of the arrow is said to represent a balanced chemical reaction.
- A chemical reaction is represented symbolically in writing by a chemical equation. The chemical(s) used as the reactant(s) are listed on the left and the chemical(s) used as the product(s) are listed on the right.
- A chemical reaction requires an equal number of atoms in the reactants and products because, according to the rule of conservation of mass, atoms cannot be generated or destroyed throughout the process.
How to balance a molecular chemical equation?
- First of all, identify the most complicated or complex substances.
- If possible, start with that material and pick an element or elements that are present in only one reactant and one product. To get the same number of atoms of this element(s) on both sides, adjust the coefficients.
- If polyatomic ions are present on both sides of the chemical equation, they should be balanced as a whole.
- The remaining atoms are then balanced, typically ending with the substance that is the least complicated and, if necessary, employing fractional coefficients.
- In order to get whole numbers for the coefficients if a fractional coefficient was used, multiply both sides of the equation by the denominator.

What is Balanced equation?
- If both the reactants and the products of a chemical reaction have the same number of atoms and total charge, the equation for the reaction is said to be balanced. In other words, the mass and charge balances on both sides of the reaction are equal.
- The equation must be balanced so that each type of atom appears in equal amounts on both the left and right sides of the arrow. This is accomplished by altering the compounds' coefficients (numbers placed in front of compound formulas).
- In an imbalanced chemical equation, the reactants and products of a reaction are provided, but the amounts required to satisfy the conservation of mass are not given.
