Alayer of sediment goes through a series of steps on its way to becoming sedimentary rock. these steps are summarized below. read the steps carefully, and then place them in the correct order. the sediment is deposited by wind, flowing water, or other natural processes. the sediment is gradually buried and compacted. dissolved minerals completely cement the sediment together. → →

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.)
