A sealed cylinder of gas contains nitrogen gas at 101.3 kPa and 20.0 degrees Celsius. When the cylinder is left in the sun, the temp of the gas increases to 50.0 degrees Celsius. Find the new pressure of the gas in the cylinder.

6.4 cm (max) - 25 cm (min)

the answer is c

tell me if wrong

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.
