Answer:
1. The skater's kinetic energy decreases as he moves up the ramp. As the skater moves down the ramp, his potential energy decreases
2.Kinetic Energy is the energy of motion. As the skateboard rolls down the ramp it loses potential energy and gains kinetic energy. The total energy of the skateboarder remains constant.

Answer:
1.2 M
Explanation:
If you use the dilution equation (M1V1=M2V2), you end up with (50)(12)=(500)(M2), and when you solve for M2 you get 1.2 M.
Explanation:
A single-replacement reaction replaces one element for another in a compound.
A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds.
A precipitation reaction is a double-replacement reaction in which one product is a solid precipitate.
Solubility rules are used to predict whether some double-replacement reactions will occur.
