Acontainer made of steel, which has a coefficient of linear expansion 11 ✕ 10−6 (°c)−1, has a volume of 41.0 gallons. the container is filled to the top with carbon tetrachloride, which has a coefficient of volume expansion of 5.8 ✕ 10−4 (°c)−1, when the temperature is 10.0°c. if the temperature rises to 28.5°c, how much carbon tetrachloride (in gal) will spill over the edge of the container?

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.)
