For this question, use the main assumptions of the kinetic molecular theory of gases:
1. gases are made up of molecules which are relatively far apart.
2. the molecules are in motion at high speeds.
3. the molecular collisions are perfectly elastic.
4. increase in temperature increases the kinetic energy of the molecules.
which of the assumptions explains the pressure which a gas exerts?
a.1
b.2
c.3
d.4
e.1 and 2
f.2 and 4

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
