Devise a detailed mechanism for formation of the major product of the substitution reaction below. Reaction
Draw curved arrows to show electron reorganization for the mechanism step below. Make the ends of your arrows specify the origin and destination of reorganizing electrons.

In this step, the alcohol is protonated creating a good leaving group.

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.)

Why does his teacher ask him to balance the equation by including the correct coefficient
