Calculate the ratio of H+ ions to OH-ions at a pH = 8. What is the concentration of H+ ions at a pH = 8? Find the concentration of Htions to OH-ions listed in mol/L Table B of your Student Guide. Then divide the H+ concentration by the OH- concentration. Record this What is the concentration of OH-ions at a pH = 8? calculated ratio in Table A of your Student Guide. mol/L Compare your approximated and calculated ratios of H* What is the ratio of H+ ions to OH-ions at a pH = 8? ions to OH-ions at a pH = 8. Are they the same? Why or :1 OR 1: why not? Record your explanation in Table A.

it should be p1 v1 = p2 v2

explanation:

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.
