<span>D. The average kinetic energy of their particles is the same.</span>
The highest concentration of hydrogen ion (H+) is located in the intermembrane space. The intermembrane space is the space between inner membrane and the outer membrane of the mitochondrion or chloroplast. THe main function of intermembrane is oxidative phosphorylation.
Reference table J?
In general though reactions happen when one element wants to replace another element in another molecule/compound. So in this case you are essentially looking for the most reactive metal of the 4 choices. Elements become more reactive as you go down the periodic table, and metals become more reactive as you move left along the period, meaning Alkali metals are the most reactive metals, and Francium is the most reactive metal.
Based on this knowledge we can assume that Potassium is the most reactive of the choices and thus most readily reacts with HCl to produce H2 gas. And if you want prood check out this video!

Prolly top left because it’s at the top. But I’m not positive because I haven’t took the whole quiz or assignment.
