A system consisting of a sample of ideal gas in a cylinder bounded by a frictionless piston. The volume of the system expanded against a constant pressure of 104802.047 mmHg so that 39.195 J of work were done by the system. During this process 53.49 J of heat energy were given off. What was the internal energy change for the system? Also, what was the enthalpy change for the system?

explanation:

ok whats the question if not i cannot you i need question and need a thing to answer

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.
