Study Notes
Chemical Reactions and Atoms
- Atoms cannot be created or destroyed during a chemical reaction, adhering to the Law of Conservation of Mass.
- It is essential to maintain the same number of atoms on both sides of a chemical reaction for balance.
Balancing Chemical Equations
- To balance a chemical equation, place a number (coefficient) in front of the chemical formulas, adjusting them as needed to ensure equal atom counts on both sides.
- Changing or adding subscripts within chemical formulas is prohibited, as it alters the chemical identity of the substances.
Components of a Chemical Equation
- Reactants are located on the left side of the equation, representing the starting materials that undergo change.
- Products appear on the right side, indicating what is formed as a result of the chemical reaction.
