Consider the velocity of the rocket. If you added a payload to this rocket, would it travel faster or slower? How is this like two gases, one heavier and one lighter, traveling at the same temperature?
PLEASE HELP AND HURRY

__can be defined as which velocity changes

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.)

In a chemical reaction at equilibrium, the rate of the forward reaction the rate of the reverse reaction. if the rate of the forward reaction more products are formed.
