Nai+pb(so4)2=pbi4+na2(so4)
how do you balance this equation

By putting a coefficient 4 on NaI and 2 on Na₂SO₄

4NaI + Pb(SO₄)₂ → Pbi4 + 2Na₂SO₄

Explanation:

A chemical equation is balanced for it to obey the law of conservation of mass.According to the law of conservation of mass, the mass of the reactants should be equal to the mass of products. Balancing involves putting coefficients on reactants and products to get an equal number of atoms of each element on either side of the equation.In this case, putting a coefficient four on NaI and two on Na₂SO₄ will make the equation to be balanced.Therefore, the balanced chemical equation is;

4NaI + Pb(SO₄)₂ → Pbi4 + 2Na₂SO₄

I'm not sure but i will try to find out
