No, they can have potential energy
Yes if you add an energy to an electron the electron will become excited, and it will jump to its highest level then go back down releasing energy
To find moles in this sample, you would divide grams by molar mass of ethyl alcohol
(18.0g)/(46.07g/mol) = 0.391mol C2H6O
Answer:
pH = 13.18
Explanation:
pOH = -log[OH-] = -log(0.15) = 0.82
pH + pOH = 14
pH = 14 - 0.82 = 13.18
