What are coefficients in a chemical equation?
gpt
Coefficients are numbers that appear before a formula in a chemical equation to balance the equation.
Explanation: In a chemical equation, coefficients are numbers placed in front of the chemical formulas of reactants or products to indicate the relative amounts of each substance involved in the reaction. They are used to balance the equation and ensure that the number of atoms of each element is equal on both the reactant and product sides.
