Question
State whether the following statement is true or false:
A chemical equation can be balanced easily by altering the formula of a reactant or product.
Advertisements
Solution
This statement is false.
Explanation:
In a chemical equation, the numbers preceding the compounds are called stoichiometric coefficients. The coefficients must be altered to achieve a balanced chemical equation. A chemical reaction is balanced by altering the stoichiometric coefficients rather than modifying the formulas of the reactants or products.
