The Earth’s circumference around the equator is slightly bulged as compared to the circumference around the poles. If the circumference around Earth’s equator is 29,902 miles, what is this in Mm?

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.)

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally
