What is a balanced equation?

A balanced equation is an equation that has the same amount of mole or atoms on both sides, the reactant, and the product. The moles of both sides of a reaction should be the same, according to the law of conservation of energy. To balance the equation, we should check the mole so both side.

Thus, the balanced equations are:

Easy

1. 2K + Br₂ → 2KBr

2. 4Sb + 3O2 → Sb₄O₆

Medium

1. 2Na + 2H₂O → 2NaOH + H₂

2. 2KNO₃ → 2KNO₂ + O₂

Hard

1. 4NH₃ + 5O₂ → 4NO + 6H₂O

2. C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
