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)

Afraidsugar lol it’s the third one

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
