2. A helium air balloon has a volume of 20 L when it's released from sea level where the pressure is 200 kPa. What will be the hot air balloon's volume when it reaches an altitude
where the pressure is 230 kPa? Write the formula first then show your math!

answerspecific gravity;

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.
