821 Identify the reactants and products of a chemical reaction

821: Identify the reactants and products of a chemical reaction Key concepts/skills: Level 1: Define key vocabulary. Level 2: Recognize all part of a chemical equation. Level 3: Distinguish between the reactants and products given chemical equations.

Key vocabulary Symbol Element Formula Compound Subscript Yield Reactant Product 821: Identify the reactants and products of a chemical reaction

I.Chemical equation – symbols, subscripts, and coefficients that describe what happens during a chemical reaction 821: Identify the reactants and products of a chemical reaction

A.Reactants – substances that combine in the chemical reaction B.Reactants are always on the left side of the arrow (sometimes separated by + sign) 821: Identify the reactants and products of a chemical reaction

C. Products – substances created by the chemical reaction D. Products are always on the right side of the equation (sometimes separated by + sign)

E. The arrow (yield sign) separates the formulas of the reactants from the formulas of the products (means “produces”) 821: Identify the reactants and products of a chemical reaction

F.Subscripts – number on the lower right of the symbol that tells how many atoms in the formula 821: Identify the reactants and products of a chemical reaction
