The two most common nutrative (caloric) sweeteners used in the manufacturing of food and beverages are sucrose and high-fructose corn syrup (hfcs). the latter is produced from corn syrup in a process that enzymatically converts a percentage of the glucose, which is the predominant sugar component, into fructose. hfcs used in most commercial food and beverage production is either 55% or 42% fructose

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.)
