To what volume will a 2.33 l sample of gas expand if it is heated from 30.0 ∘c to 300.0 ∘c?

The gas will expand to the final volume of 4.406 L.

According to Charles law, on heating a gas, the ratio of Volume to temperature remains constant.

where V1 and T1 are initials

V2 and T2 are final.

So, final volume =

Final volume =

Final volume = 4.406 L.

The gas will expand to the final volume of 4.406 L.

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

the awnser is group 12
