The diagram below shows different layers of sedimentary rocks.
picture showing seven layers of rocks of different colors labeled a, b, c, d, e, f, and g from top to bottom; a and b are parallel horizontal layers at the top of the diagram and c, d, e, f, and g are slanted layers with c closest to the surface and g at the bottom.
based on the diagram, which of these inferences is most likely correct?
a. layer a is older than layer b.
b. layer c is older than layer e.
c. layer f is younger than layer d.
d. layer b is younger than layer g.

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
