Is 2Na plus S and 2NaS considered a balanced equation?

Answer 1

Consider firstly if there are equal numbers of atoms of each element on either side of the reaction. No, there aren't: there are too many sodium, chloride ions and hydrogen atoms on the reactant side, so the equation is not balanced.

Answer 2

No, the equation 2Na + S → 2NaS is not balanced because the number of sodium atoms on each side is different. On the left side, we have 2 sodium atoms, while on the right side, we have 2 sodium atoms in the compound NaS. The equation should be balanced by adjusting the coefficients to ensure the same number of atoms of each element on both sides.

Answer 3

Na2S is not an equation in itself. However, it is a molecule with zero charge, which is what I think you are getting at.

Answer 4

Yes
