--- Quote from: biology1234 on February 16, 2022, 06:16:06 pm ---what would the electron configuration be for K +, potassium. I got this, 1s2 2s2 2p6 3s2 3p6 4s1. My answer book got 1s2 2s2 2p6 3p6. Would it not loose an electron as potassium is in group 1, and only need 18 electrons. Could someone explain

Your answer is correct only for a neutral K atom (19 protons balanced by 19 e-s). For a K+ ion, it will lose one e- from the 4s orbital, so it only has 18 e-s

Which of the following statements about atp synthase is correct?
A atp synthase is located in the inner membrane of the mitochondrion
B atp synthase is located in the cytosol
C atp synthase is involved in glycolysis
D atp synthase is involved in electron transfer
Is this a but would d also be correct

The answer is A. D is incorrect because ATP synthase is not involved in electron transfer as it is not in the electron transport chain. Rather, it interacts with protons and catalyses the production of ATP.

HELPPPP!!!!
I DONT GET MOLES/RELATIVE ATOMIC MASS/EVERYTHINGGGGGG
I CANT SEEM TO GRASP THE CONCEPT AT ALL
I don't get N vs n vs m vs M
I need a review over everything
arnavg2207:
Hey, for combustion reactions and thermochemical equations I was wondering if you give the state of water as (l) or (g)? The answers seem to be inconsistent (for the combustion of octane one gives it as liquid while the other gives it as solid)
Thanks!
