Balance the following equations. (b) The spoilage of wine into vinegar: C₂H₆O + O₂ → C₂H₄O₂ + H₂O

Balancing chemical equations involves ensuring that the number of atoms for 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. To balance an equation, coefficients are adjusted in front of the chemical formulas to achieve equal atom counts.

The spoilage of wine into vinegar is an example of an oxidation-reduction (redox) reaction, where one substance is oxidized (loses electrons) and another is reduced (gains electrons). In this process, ethanol (C2H6O) is oxidized to acetic acid (C2H4O2), and oxygen (O2) acts as the oxidizing agent. Understanding redox reactions is crucial for predicting the behavior of reactants and products in chemical transformations.

Stoichiometry is the calculation of reactants and products in chemical reactions based on balanced equations. It allows chemists to determine the proportions of substances involved in a reaction, which is essential for predicting yields and understanding reaction dynamics. In the context of the given equation, stoichiometry helps in identifying the correct coefficients needed to balance the reactants and products.
