Detailed explanation-1: -In Chemistry the coefficient is the number in front of the formula. The coefficient tells us how many molecules of a given formula are present. 2H2O means we have 2 molecules of water. In the balanced chemical equation for Ammonia.
Detailed explanation-2: -The numbers placed in front of formulas to balance equations are called coefficients, and they multiply all the atoms in a formula.
Detailed explanation-3: -The numbers are called coefficients. A chemical equation uses coefficients, whole numbers written in front of reactants or products, to balance the equation.
Detailed explanation-4: -The number of atoms of each element in a chemical formula is designated by the small number behind each element symbol. If there is no number, it is assumed there is only one of that element. A large number in front of a compound designates how many units there are of that compound.
Detailed explanation-5: -Hint: Coefficients are the numbers or terms used to balance chemical equations and are placed in front of a chemical symbol or formula. It tells us about how many atoms or molecules of substance or compound are involved in the reaction.
