Step 4 What is the concentration of Htions at a pH = 8?
mol/L
Calculate the ratio of H+ ions to OHions at a pH = 8.
Find the concentration of H+ ions to OH-ions listed in
Table B of your Student Guide. Then divide the Ht
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 = 8. Are they the same? Why or
why not? Record your explanation in Table A.

What is the ratio of H+ ions to OH-ions at a pH = 8?
:1 OR 1:

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

wher is the rest of the question

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
