Two gas samples have the same number of molecules. it is most likely that the two gas samples have:

a. the same volume only.
b. different volume and pressure.
c. the same volume, pressure, and temperature.
d. the same volume, and pressure, but a different temperature.

The answer is C.)

Hope this helps. I took the test and it was correct!

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
