The balanced equation has a proportionate number of atoms on both sides of the reaction. In the reaction between lead nitrite and zinc bromide, the coefficient of PbBr₂ is 1. Thus, option C is correct.
What is a balanced equation?
A balanced equation is the representation of the elements and the compounds of the reactants and the product side in the symbolic forms along with their balanced coefficients.
The coefficient of the element on the right and the left side of the reaction must be the same in order for the reaction to be balanced. The balanced reaction between zinc bromide and lead nitrite is shown as,
ZnBr₂ + Pb(NO₂)₂ → Zn(NO₂)₂ + PbBr₂
Here, the number of zinc, lead, and nitrogen dioxide is 1 on both the reactant and product side, whereas bromine is two on both sides.
Therefore, in option C. the coefficient in front of PbBr₂ is 1.
