PLEASE ANSWER

These two blocks have the same mass. Which block would have more kinetic energy when it reaches the ground and why?

A. Block B would have more kinetic energy since it is traveling faster. than block A

B. Block B would have more kinetic energy since it is closer to the ground. and doesn't have as much potential energy.

C. Block A would have more kinetic energy since it is higher and has more potential energy to transform into kinetic energy.

D. Block A would have more kinetic energy since it has more mass than block B.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
