Predict the polarity of 6 real molecules. first, draw the molecules and any bond dipoles. then draw any molecular dipoles. explain your reasoning before you check your predictions with the simulation.

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.)
