Imagine that you have an ideal gas in a 4.30 L container, and that 1250 molecules of this gas collide with a square-inch area of the container at any given instant. If the volume is increased to 21.5 L at constant temperature, how many collisions will occur per square inch of this larger container

250 collisions per square inch

Explanation:

According to Boyle's law, at constant temperatures, the pressure exerted by gas molecules is inversely proportional to the volume of the gas. Hence;

    P1V1 = P2V2 where P1 = initial pressure, V1 = initial volume, P2 = final pressure, and V2 = final volume

In this case, the collision that occurred is taken as the pressure.

P1 = 1250, V1 = 4.30 , V2 = 21.5 P2 = ?

P2 = P1V1/V2

        = 1250 x 4.30/21.5

                 = 250

Hence, at a constant temperature, 250 collisions per square inch of the larger container will occur.

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.
