The formation of an ionic bond involves a number of different processes. in the formation of sodium chloride, represented by the equation given below, two steps result in a release of energy. choose those two steps. (yes, you fill in two bubbles on your scantron for this question. you must choose both correct answers to receive credit for the question.) 2na(s) + cl2(g) → 2nacl(s) a. attraction of na+ and cl– to form nacl. b. removal of an electron from na. c. the addition of an electron to each cl atom d. conversion of na(s) to na(g). e. dissociation of cl2 to form 2 cl atoms.

            The two steps which results in the release of energy are;

                 A)  Attraction of Na⁺ and Cl⁻ to form NaCl

                 C)  The addition of an electron to each Cl atom

Explanation:
                   As we know Born Haber Cycle is helpful in measuring the Lattice Energies of Crystal systems indirectly. So, the formation of NaCl crystal takes place in several steps. Among all steps, The formation of Chloride ions (Electron Affinity) and binding of Na⁺ and Cl⁻ (Lattice Energy) are exothermic in nature, while remaining all steps require energy to proceed (Endothermic).

Although the diagram is not shown, i know that the convection is heated by a the core.

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)
