Key Concepts

Conservation of Mass

This fundamental concept in chemistry states that matter cannot be created or destroyed in a chemical reaction. When balancing chemical equations, the number of atoms for each element must be equal on both sides of the equation, ensuring that the total mass remains constant throughout the reaction.

Stoichiometry

Stoichiometry involves the quantitative relationships between reactants and products in a chemical reaction. It uses the coefficients in a balanced chemical equation to represent the proportional amounts of each substance involved, which is essential for predicting yields and scaling reactions.

Balanced Chemical Equation

A balanced chemical equation is one in which the number of atoms of each element in the reactants matches the number in the products. Adjusting coefficients in the equation is the primary method used to achieve this balance, reflecting the real-life conservation of matter and allowing accurate chemical calculations.
