###### FREE Expert Solution

Before balancing the chemical reaction, let’s first write the chemical formula of the compounds involved in the reaction.

Reactants:

▪ Lead (II) → +2 charge → Pb+

▪ Nitrate ion → -1 charge → NO3

▪ Combine both ions, the charge of the ion goes to the subscript of the counterion
