In a reaction vessel, 0.600 mol of Ba(NO3)2 and 0.300 mol of H3PO4 are combined with deionized water to a final volume of 2.00 L. The reaction represented below occurs: 3 Ba(NO3)2(aq) +2 H3PO4(aq) - Baz(POA)(s) + 6 HNO3(aq) (a) Calculate the mass of Ba3(PO4)2 formed. (b) Calculate the initial molarity of Ba(NO3)2 and H3PO4 (c) Calculate the molarity of the NO3 ion after the reaction reaches completion.​

c. orbital shape i hope this is correct

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.
