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.)

20 look at the clock and the data table below. based on the data and on your knowledge of potential and kinetic energy, what is the best conclusion you can make about potential and kinetic energy? the total amount of energy stays the same. the clock has the most potential energy at point b since it is moving the fastest. there is always more potential energy than kinetic energy. potential energy can never be 0, but you can have 0 kinetic energy.
