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.
ContainerA
O
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.
DONE
Container B

The zinc within a copper-plated penny dissolves in hydrochloric acid if the copper coating is filed down in several spots (so that the hydrochloric acid can reach the zinc). the reaction between the acid and the zinc 2h+(aq)+zn(s)→h2(g)+zn2+(aq) . when the zinc in a certain penny dissolves, the total volume of gas collected over water at 25 °c is 0.947 l at a total pressure of 743 mmhg . (vapor pressure of water is 23.78 mmhg at 25 °c .) what mass of hydrogen gas is collected? answer in appropriate significant figures
