2agl+na2s ag2s+2nal is it balanced or unbalanced

It is balanced

Explanation:The equation, 2AgI+Na₂S → Ag₂S+2NaI, is balanced because the number of atoms of each element is equal on both sides of the equation.That is, there are two silver atoms, two iodide atoms, two sodium atoms, and one sulfur atom on the right and left the side of the equation.According to the law of conservation of mass, chemical equations should be balanced for the mass of reactants to be equal to that of the products.
