An air conditioner is designed to bring 10,000ft3/min of outside air (90°F, 29.8 inches Hg, 88% relative humidity)to40°F,,andthentoreheatthe air before releasing it into a room at 65°F. Calculate the rate of condensation (gallons H2O/min) and the volumetric fl.(Suggestion: Onthe flowchart, treatthecooling– condensation and the reheating as separate process steps.)

the awnser is group 12

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.
