A chemist wants to extract copper metal from copper chloride solution. The chemist places 1.50 grams of aluminum foil in a solution of 14 grams of copper (II) chloride. A single replacement reaction takes place. What best explains the state of the reaction mixture after the reaction?
Unbalanced equation: CuCl2 + Al → AlCl3 + Cu (5 points)
a. Less than 6.0 grams of copper is formed, and some aluminum is left in the reaction mixture.
b. More than 6.5 grams of copper is formed, and some aluminum is left in the reaction mixture.
c. Less than 6.0 grams of copper is formed, and some copper chloride is left in the reaction mixture.
d. More than 6.5 grams of copper is formed, and some copper chloride is left in the reaction mixture.

The equilibrium constant kc for the reaction 2 nocl(g) → 2 no(g) + cl2(g) is 0.453 at a certain temperature. a mixture of nocl, no, and cl2 with concentrations 1.30, 1.20, and 0.600 m, respectively, was introduced into a container at this temperature. which of the following is true? 1. no apparent reaction takes place. 2. [cl2] = 0.30 m at equilibrium. 3. nocl(g) is produced until equilibrium is reached. 4. [nocl] = [no] = [cl2] at equilibrium. 5. cl2(g) is produced until equilibrium is
