📖 Balancing Examples
Simple oxidation:
Unbalanced: Al + O2 → Al2O3
Balanced: 4Al + 3O2 → 2Al2O3
Aluminum: 4 = 4, Oxygen: 6 = 6
Unbalanced: Al + O2 → Al2O3
Balanced: 4Al + 3O2 → 2Al2O3
Aluminum: 4 = 4, Oxygen: 6 = 6
Organic reaction:
Unbalanced: C2H6 + O2 → CO2 + H2O
Balanced: 2C2H6 + 7O2 → 4CO2 + 6H2O
C: 4=4, H: 12=12, O: 14=14
Unbalanced: C2H6 + O2 → CO2 + H2O
Balanced: 2C2H6 + 7O2 → 4CO2 + 6H2O
C: 4=4, H: 12=12, O: 14=14

Frequently Asked Questions
What does it mean to balance a chemical equation?
Balancing an equation means finding coefficients in front of substance formulas so that the number of atoms of each element is equal on both sides of the equation.
Why is it important to balance chemical equations?
Balancing equations reflects the law of conservation of mass - the mass of substances before reaction equals the mass after reaction. This is the foundation of all chemical calculations.
How does the calculator find coefficients?
The calculator uses mathematical methods to solve a system of linear equations representing the balance of each element in the reaction.
Can any equation be balanced?
Most chemical equations can be balanced, but some reactions may require additional information about conditions or reaction mechanism.
What to do if equation doesn't balance?
Check the correctness of substance formulas, ensure the reaction is chemically possible, or try splitting complex reactions into several simple ones.
