Arsine, AsH3, is a highly toxic compound used in the electronics industry for the production of semiconductors. Its vapor pressure is 35 torr at -111.95 degree C and 253 torr at -83.6 degree C. Calculate the delta H of vaporization for arsine and its normal boiling point.
Answers: 3
of vaporization for arsine and its normal boiling point is, 17694.3 J/mol and 209.9 K respectively.
= vapor pressure of arsine at 
= 35 torr
= vapor pressure of arsine at 
= 253 torr
= temperature of arsine = 
= temperature of arsine = 
= heat of vaporization = ?

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.)
