An enantiomer is presented below in a 3d structure and in an unfinished 2d representation. a) on the 3d structure, select – by clicking on – the chirality center. a selected atom will be outlined in blue. b) examine the 3d structure below to determine the stereochemistry of the chiral molecule. then, on the corresponding 2d structure, draw one wedge bond and one dash bond over two existing bonds to indicate the correct stereochemistry. the narrow part of each wedge-and-dash bond should be towards the chirality center.

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
