In the process of oxidizing i− to i2, so42− is reduced to so2. how many moles of so2 are produced in the formation of one mole of i2? express your answer numerically in moles.

Is this a single replacement reaction or there is no

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.)
