About Chemical Equation Balancing
What is Balancing?
Balancing a chemical equation means adjusting coefficients so that the number of atoms of each element is equal on both sides of the equation. This follows the Law of Conservation of Mass.
Key Principles
- Atoms Conserved: No atoms are created or destroyed in a reaction
- Coefficients: Numbers placed in front of compounds (1 is implied if no number)
- Subscripts: Numbers in chemical formulas cannot be changed
- Both Sides Equal: Same number of each element on both sides
Balancing Steps
- Write the unbalanced equation
- Count atoms on each side
- Add coefficients to balance
- Verify all elements are balanced
- Use smallest whole numbers
