In the solar system some planets composed mostly of gas and liquid and some planets are composed mostly of solid rock. Which statement about these two kids of planets and their relative size and sigan e from the sun is correct ?

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.)
