The balanced equation is 2 Pb (NO3)2 → 2PbO + 4NO2 + O2. Steps to balance this Pb (NO3)2 → PbO + NO2 + O2 equation:

Step 1: Given the equation:

Pb (NO3)2 → PbO + NO2 + O2

Step 2: Method used for balancing the equation:

  • utilising the standard approach for balancing chemical equations. First, compare the atoms of every element on the product and reactant side, according to the technique.
  • Molecules containing an element with a distinct number of atoms on the product and reactant side should be given stoichiometric coefficients. The number of atoms on either side must be balanced by the coefficient.
  • Typically, the oxygen and hydrogen stoichiometric coefficients are assigned at the end.
  • The stoichiometric coefficient must be multiplied by the total number of atoms of an element present in 1 molecule of the species to determine the number of atoms in one species.
  • Continue doing this until both the reactant and product sides have the same number of all the atoms of the reacting components.

Step 3: Achieving equation balance:

The equation is as follows: Pb (NO3)2→ PbO + NO2 + O2

Reactant side:

  • 1 Lead atom
  • 2 Nitrogen atoms
  • 6 Oxygen atoms

Product side:

  • 1 Lead atom
  • 1 Nitrogen atom
  • 5 Oxygen atoms

The oxygen atoms are balanced first. After being balanced, the equation is: 2 Pb (NO3)2 → 2PbO + 4NO2 + O2

The lead and nitrogen atoms are then balanced. The revised equation is: 2 Pb (NO3)2→ 2PbO + 4NO2 + O2

Reactant side:

  • 2 Lead atom
  • 4 Nitrogen atoms
  • 12 Oxygen atoms

Product side:

  • 2 Lead atom
  • 4 Nitrogen atom
  • 12 Oxygen atoms

The equation is balanced because there are an equal number of all the atoms of the reacting components on both the product and reactant sides.

So, the equation that is balanced is: 2 Pb (NO3)2 → 2PbO + 4NO2 + O2

Summary:

Balance this Equation: Pb (NO3)2 → PbO + NO2 + O2

The balanced equation of Pb (NO3)2 → PbO + NO2 + O2is 2 Pb (NO3)2 → 2PbO + 4NO2 + O2. A balanced chemical formula has the same number of atoms on the reactant and product sides of each element involved in the reaction.
