Answer:
it means compound A is <u>less</u> polar than compound B
Explanation:
It is sure that the more polar the solvent, the faster compounds elute, regardless of the compounds polarity. This means changing the solvent polarity cannot change the order compounds elute from a TLC or column. This may seem non intuitive, as it would seem that a polar solvent would move a polar compound farther than a nonpolar compound.
Answer:
The Artic Ocean
Explanation:
it is mostly surrounded by land with only a bit of exchange of water with the other oceans
According to Bronsted-Lowry theory acid are donor of protons and bases are acceptors of protons (the hydrogen cation or H⁺).
1) NH₄⁺(aq) + H₂O(l) ⇄ NH₃ + H₃O⁺(aq); the ammonium cation (NH₄⁺) gives proton to water.
2) [Co(H₂O)₆]³⁺ + H₂O ⇌ [Co(H₂O)₅(OH)]²⁺ + H₃O⁺; cobalt cation (Co³⁺) forms complex cation with six molecules of water, which act like acid and gives protons.
3) CH₂NH₃⁺(aq) + H₂O(l) ⇄ CH₂NH₂ + H₃O⁺(aq); H⁺ is cationic form of atomic hydrogen, the hydrated form of the hydrogen cation is the hydronium ion H₃O⁺(aq).
