Pairs of magnets are shown in the diagram. Bar magnets lined up vertically side by side in pairs. The first pair is labeled W with the north pole beside the south pole of the second. The second pair is labeled X and vertical with the north pole of one near the north pole of the other. The third pair is labeled Y with the south pole of one near the north pole of the other. The last pair is labeled Z and are lined up side by side. The south pole of one is beside the north pole of the second. Which pair of magnets is aligned so they will repel each other?

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
