Introduction to Chemical Equations
Chemical equations are symbolic representations of chemical reactions. They provide a concise way to describe the reactants, products, and the stoichiometry of a reaction. The reactants are the starting materials, while the products are the substances formed in the reaction.
Coefficients in front of the chemical formulas indicate the relative amounts of each reactant and product.
Chemical equations also include information about the physical states of the reactants and products, such as solid (s), liquid (l), gas (g), or aqueous (aq). By convention, aqueous solutions are represented by the symbol (aq) after the chemical formula.
Balancing Chemical Equations
Balancing chemical equations is essential to ensure that the number of atoms of each element is the same on both sides of the equation. This reflects the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
There are several methods for balancing chemical equations. One common method is to start by balancing the most complex molecule in the equation. Coefficients can be adjusted in front of each chemical formula until the number of atoms of each element is the same on both sides.
