Calculate the pH of a (0.000765) M solution of KOH

pH = - log(0.000765)

= -(-3.11)

= 3.1

so the solution is basic

rest you can check values using calculator

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.

mark brainliest and have a great day!
