How much heat energy is required to completely change 25 grams of ice at 0 degree Celsius to water and raise the temperature to body temperature at 37 degree Celsius

a polar bond is formed when electrons are shared unevenly between atoms

pv=nrt

explanation:

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.
