A spray can is used until it is empty except for the propellant gas, which has a pressure of 1307 torr at 23°C. If the can is thrown into a fire (T = 477°C), what will be the pressure (in torr) in the hot can

Explanation:

Hello!

In this case, since here we have a pressure-temperature relationship, we need to use the Gay-Lussac's law in order to compute the final pressure as they are in a directly proportional relationship:

Now, we plug in the given pressure and temperatures in Kelvins to obtain:

Best regards!

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.
