Abrine solution of salt flows at a constant rate of 99 l/min into a large tank that initially held 100100 l of brine solution in which was dissolved 0.10.1 kg of salt. the solution inside the tank is kept well stirred and flows out of the tank at the same rate. if the concentration of salt in the brine entering the tank is 0.020.02 kg/l, determine the mass of salt in the tank after t min. when will the concentration of salt in the tank reach 0.010.01 kg/l?

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.
