Applying Information about Gases QUICK CHECK
The diagrams to the right show the distribution
and arrangement of gas particles in two different
containers. According to kinetic-molecular theory,
which of the following statements is true? Check
all that apply.
If the temperatures of both containers are
equal, container A has greater pressure than
container B.
If the volume of container A decreased its
pressure would decrease.
If the pressure in both containers is equal,
container A has a lower temperature than
container B.

Compare the valence electron configuration of the nobles gas elements seen here. what statement is correct?

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.)

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?
