Key Concepts

Balanced Equations

Balanced equations are chemical equations in which the number of atoms of each element is the same on both the reactant and the product sides. This balance reflects the law of conservation of mass, ensuring that matter is neither created nor destroyed during the reaction.

Reaction Diagram Interpretation

Interpreting a reaction diagram involves translating a visual representation of a chemical process into a balanced chemical equation. This requires understanding the relative proportions of reactants and products indicated in the diagram and choosing the corresponding stoichiometric coefficients.

Chemical Reaction

A chemical reaction represents the process in which reactants are transformed into products. The reaction is typically written as a chemical equation that uses symbols and formulas to denote the substances involved and indicates the direction of the reaction.

Stoichiometry

Stoichiometry is the quantitative relationship between reactants and products in a chemical reaction. It involves using the mole ratios derived from a balanced chemical equation to determine the amounts of each substance involved in the reaction.
