Chemical Equations
Chemical equations serve as concise representations of chemical reactions, encapsulating the transformation of reactants into products. They consist of chemical formulas symbolizing the participating elements and compounds, along with coefficients indicating the relative quantities of each substance. These equations adhere to the law of conservation of mass, ensuring that the total mass of reactants equals that of products. By elucidating the fundamental changes occurring during chemical reactions, chemical equations provide a foundational framework for understanding the principles of chemistry and predicting outcomes in various chemical processes.
