Chemical Reactions

Subject: Chemistry

Book: General Chemistry

A chemical reaction involves the rearrangement of atoms to form new substances, converting reactants into products. Indicators of chemical change include gas production, color change, and energy release or absorption. Equations like CH4 + 2O2 → CO2 + 2H2O represent the process symbolically. Types of reactions include synthesis, decomposition, single displacement, double displacement, combustion, and redox. Understanding reaction types is crucial for predicting products and managing reaction conditions.
