Companies may draw water from nearby sources, including the ocean, to cool industrial equipment. After the water has passed through or over their equipment, it is returned to its source. The heated water contains less oxygen than cool water. What happens when companies expel heated water into the ocean?

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.)
