What is the volume of a gas at 90 degrees celsius, if it occupies 1.41L at 170 degrees celsius

1.15 L

Explanation:

Working under the assumption that this takes place at constant pressure, Charles Law ; V1/ T1 = V2/T2 would be applied.

V1 = Initial Volume = 1.41L

V2 = Final Volume = ?

T1 = Initial Temperature = 170 ° C , which is (273.15 + 170)K = 443.15K

T2 = Final Temperature = 90 ° C, which is (273.15 + 90 )K =  363.15K

∴ Making V2 subject of the formular, we then have;

  V2 = V1 x T2 / T1 = 1.4L  x 363.15K / 443.15K

       = 508.41/ 443.15 = 1.15 L

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
