Astronauts measured a rock on the moon. Its mass was 1,500g and its volume was 250cm. How
does the density of the rock change on Earth?
A)It would increase dues to volume expansion.
B)Density increases because its weight increases on Earth.
c)It would decrease due to decreased gravity acting on its volume.

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.)
