Balance the following equations. (c) S + O₂ → SO₃

Key Concepts

Balancing Chemical Equations

Balancing chemical equations involves ensuring that the number of atoms of each element is the same on both sides of the equation. This is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Coefficients are used to adjust the quantities of reactants and products to achieve balance.

Stoichiometry

Stoichiometry is the study of the quantitative relationships between the amounts of reactants and products in a chemical reaction. It allows chemists to predict how much of each substance is needed or produced in a reaction. Understanding stoichiometry is essential for balancing equations, as it provides the ratios in which substances react and form.

Combustion Reactions

Combustion reactions typically involve a substance reacting with oxygen to produce energy, carbon dioxide, and water. In the case of sulfur reacting with oxygen, the product is sulfur trioxide (SO3). Recognizing the type of reaction helps in predicting the products and understanding the balancing process, as different reactions may have specific patterns.
