Since it goes to completion, we can use:
Use NaMaVa =NbMbVb
where
Na= moles of H+ in H2SO4
Ma= molarity of the acid
Va= volume of the acid
Nb= moles of OH- in NaOH
Mb= molarity of the base
Vb= molarity of the base
plug in the numbers
(2 moles of H+) (Volume acid) (10.00mL acid) = (1 mole of OH-) (.248M base) (18.71mL base)
20 V = 4.64
V= .232 M
I am pretty sure that the answer is A, because the element's atomic number is how many protons, maybe the neutrons, it has in it and all elements need 18 protons to make it stable. So the answer is A.
Hope that helps.

Could you mark me as brainliest?
1.F, 2.E, 3.I, 4.H,5.D,6.G, 7.A, 8.C, 9.B i hope that’s right
