Barium is a chemical element with symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element. Thanks and I hope it helped.
7 protons. As well as in nitrogen-14. The difference between nitrogen-14 and nitrogen-15 is in a number of neutrons. In nitrogen-14 - 7 neutrons, in nitrogen-15 - 8 neutrons.

Explanation:
Answer:
the heat is circulating in the same spot rather than airing out into the open
Explanation:
The equation ΔHsoln = ΔH1+ΔH2+ΔH<span>3 means that either the solution is endothermic (</span>ΔH < 0, the resulting reaction is cold) or exothermic (ΔH>0, the resulting reaction is hot). The lattice energy can be solve through this equation,
<span>lattice energy = </span>ΔHsolvation - IMF - ΔHsoln<span>
</span>
