What happens in a reaction if it is at chemical equilibrium? 1)The rate of the forward reaction exceeds that of the reverse reaction.

2)All of the products are used up.

3)The rate of the forward reaction equals the rate of the reverse reaction.

4)The rate of the reverse reaction exceeds that of the forward reaction.

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.)
