Which set of compounds illustrates the law of multiple proportions? so2, so3 h2o, h2o2 n2o, no, no2 all of these?

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.)

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3
