When we combine sodium and chlorine, they just "fit." This means both atoms are happy and the resulting ratio is 1:1. What is the net charge of the resulting ionic compound?

What is impossible to do with a hypothesis

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
