D Molecules in an ice cube have lower kinetic
energy than molecules in a radiator.
Molecules in an ice cube move more slowly
than molecules in a radiator. They collide with
less force than molecules in a radiator.
When in direct contact, the fast-moving
molecules in the radiator collide with the
slow-moving molecules in the ice cube.
Kinetic energy is transferred from the
molecules in the radiator to the molecules in
the ice cube, causing a slowdown of the
radiator molecules and an acceleration of the
ice molecules

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
