Asap what is the best name for this molecule? explain your naming process. a hydrocarbon compound with a total of 9 carbons that includes one double bond and the rest single bonds. there are 6 carbons across the bottom with 3 carbons branching off of the third carbon from the left. the double bond occurs between the 5th and 6th carbon in the bottom chain.

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.)
