Which answer best describes what is happening in the following reaction?
2C8H18 + 25O2 Right arrow. 16CO2 + 18H2O
This is not a redox reaction. It is an example of combustion.
This is a redox reaction in which octane (C8H18) is oxidized.
This is a redox reaction in which carbon dioxide (CO2) burns due to ignition.
This is not a redox reaction, because a solution of carbon dioxide and water results.

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.)
