Question

Pb3O4-----------PbO + O2 (balanced it)

Answer 1

2 Pb₃O₄ = 6 PbO(s) + O₂...
IS THE BALANCED EQUATION FOR
 Pb3O4-----------PbO + O2
REACTION TYPE =DECOMPOSITION

Answer 2

The balanced equation will be $2Pb_{3} O_{4} =6 PbO + O2$.

• While writing a chemical equation we can write it in two different ways, unbalanced and Balanced chemical reaction.
• In an unbalanced chemical reaction, the number of atoms in the reactant may not be equal to the number of atoms in the product. Example: $Al+O_{2} \ = > Al_{2} O_{3}$.
• In a balanced chemical reaction, the number of atoms in the reactant must be equal to the number of atoms in the product. Example: $4 Al+3O_{2}=2Al_{2}O_{3}$.
• In the given equation $Pb_{3}O_{4}\ = > PbO+O_{2}$, on the reactant side, the number of Pb atoms is 3 and the number of O atoms is 4 and on the product side, the number of Pb atoms is 1 and the number of O atoms is 3. So, this chemical reaction is unbalanced.
• If we write $2Pb_{3}O_{4}$ on the reactant side and $6 PbO$ on the product side, we can check the reaction will be balanced.
