Learning to calculate the metrics of chemical equations is a main challenge in chemistry. The reaction between copper(II) chloride dihydrate and aluminum must occur in an aqueous environment...true, but the masses of each individual reactant and the volume of water must be known to dissect the reaction mixture and any left over reactants, as well as the concentration of ions in the solution. The following amount of copper(II) chloride dihydrate and aluminum were combined, in a specified volume of water. Mass CuCl2 . 2H2O = (2.00x10^0) g Mass Aluminum = (1.0x10^-1) g Volume of water = (9.700x10^1) mL Molar mass of copper = 63.55 g/mol Molar Mass of aluminum = 27.00 g/mol Molar Mass of copper(II) chloride dihydrate= 170.45 g/mol

During electrophilic aromatic substitution, a resonance-stabilized cation intermediate is formed. Groups, already present on the benzene ring, that direct ortho/para further stabilize this intermediate by participating in the resonance delocalization of the positive charge. Assume that the following group is present on a benzene ring at position 1 and that you are brominating the ring at positon 4. In the box below draw the structure of the resonance contributor that shows this group actively participating in the charge delocalization. HC • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading.
