Need some help with this chemistry question! super stuck with the method please help! 7. Given that the second protonation of H2SO4 has a Ka value of 1.2 x 10-2. A H2SO4 bottle is labelled 70 % w/v concentration. Calculate the pH produced by the acid. (ANS: 0.85)

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
