It's Oxygen.
electronegativity is an arbitrary measure of how much will an electron get attracted to an atom of an element
as we know, oxygen is the best at accepting electrons from this list, so the answer is oxygen
Answer:
I'm pretty sure the net force is 200 N and the direction of motion is left
Explanation:
500 - 300 = 200 and more force is coming from and pulling toward the left.
Answer:
32
Explanation:
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
Answer : The pH of calcium acetate solution will be 9.38.
Explanation : When calcium acetate dissocates completely in solution to form Calcium(+2) ions and two acetate ions, this gives the acetate ion concentration as
(2 X 0.51 M) = 1.02 M
Acetate ion then hydrolyzes as follows;
:
Now, Kb will be = ![[HC_{2}H_{2}O_{2}] [OH^{-}]](https://tex.z-dn.net/?f=%20%5BHC_%7B2%7DH_%7B2%7DO_%7B2%7D%5D%20%20%5BOH%5E%7B-%7D%5D)
/ ![[C_{2}H_{3}O_{2}^{-}]](https://tex.z-dn.net/?f=%5BC_%7B2%7DH_%7B3%7DO_%7B2%7D%5E%7B-%7D%5D%20)
= Kw / Ka
= 1 x 
/ 1.8 x 
= 5.6 × 
![[OH^{-}]](https://tex.z-dn.net/?f=%20%5BOH%5E%7B-%7D%5D%20)
= 2.4 ×
Now, we know , pOH = -log = 4.62
So, the pH = 14 - pOH = 14 - 4.62 = 9.38
