draw the reactants and products of the following reaction (draw the structural formula):
3-ethyl-2-heptene + hoh → 3-ethyl-3-heptanol + 3-ethyl-2-heptanol
a. consider how it is possible for two products to form in this reaction, and identify the major product, giving your reasons for both.
b. what type of reaction is this classified as?

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
