Understanding Reactants and Products in Chemical Reactions

This guide provides a comprehensive overview of identifying reactants and products in chemical reactions. It defines key vocabulary such as symbols, elements, formulas, and compounds. Learn how to recognize all parts of a chemical equation, distinguish between reactants and products, and understand the role of subscripts and coefficients. Reactants are the substances that combine on the left side of the equation, while products, created by the reaction, appear on the right side. Mastering these concepts is essential for understanding chemical processes.

Presentation Transcript

  1. 821 Identify the reactants and products of a chemical reaction

  2. 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.

  3. 821: Identify the reactants and products of a chemical reaction Key vocabulary Symbol Element Formula Compound Subscript Yield Reactant Product

  4. 821: Identify the reactants and products of a chemical reaction • Chemical equation – symbols, subscripts, and coefficients that describe what happens during a chemical reaction

  5. 821: Identify the reactants and products of a chemical reaction • Reactants – substances that combine in the chemical reaction • Reactants are always on the left side of the arrow (sometimes separated by + sign)

  6. 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)

  7. 821: Identify the reactants and products of a chemical reaction E. The arrow (yield sign) separates the formulas of the reactants from the formulas of the products (means “produces”)

  8. 821: Identify the reactants and products of a chemical reaction • Subscripts – number on the lower right of the symbol that tells how many atoms in the formula

  9. 821: Identify the reactants and products of a chemical reaction
