Answer:
s orbital
Explanation:
it has the lowest energy because
Paulis law state that orbitals with lower energy must be fill first before that of higher energy
and the s orbital is filled first
Answer: Use the titration formula
Explanation:
I believe it is pentane..Try that!
Hope it helps, sorry if it doesn't but that's the answer I just choose for my unit test on edgnty.
175.8 g NaCl to moles:
(175.8 g)/(58.44 g/mol) = 3.008 mol NaCl
Molarity = moles of solute/volume of solution in liters
(3.008 mol NaCl)/(1.5 L) = 2.0 M.
The molarity of this solution would be 2.0 M.
Answer:
25
Explanation:
mass number = protons + neutrons
= 13 + 12 = 25
