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)

Less than 6.0 grams of copper is formed, and some aluminum is left in the reaction mixture.

More than 6.5 grams of copper is formed, and some aluminum is left in the reaction mixture.

Less than 6.0 grams of copper is formed, and some copper chloride is left in the reaction mixture.

More than 6.5 grams of copper is formed, and some copper chloride is left in the reaction mixture.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
