When table salt (NaCl) is added to water, it lowers the freezing point is more salt is added, the freezing point decreases even
more. Why does this occur?
A. When salt is added to water, two jons dissolve, which allows water molecules to more quickly crystallize.
B. When salt is added to water, the dissolved ions interfere with the water molecules aligning to form a solid.
C. When a salt solution is formed, sodium and chloride ions aid water in hydrogen bonding.

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.)
