In order for a molecule to exist in a stable bond, the prefered overall charge is neutral. Na is a positive one charge and Cl is negative, therfore it is neutral.
Hey there!
Given the reaction:
B + H⁺ => HB⁺
At half-equivalence point : [B] = [HB⁺]
=> [B] / [HB⁺] = 1
Henderson-Hasselbalch equation :
pH = pKa + log ( [B] ) / ( HB⁺)]
pH = 14 - pKb + log ( 1 )
pH = 14 - 7.95 + 0
pH = 6.05
Answer C
Hope that helps!
Oceans, they are larger than ponds hence they possess wider exposure with more number of surface molecules.

Answer:
Equilibrium constant (K) is defined as the ratio of concentration of product to concentration of reactant.
For the reaction: 2H2O(g) ↔ 2H2(g) + O2(g)
Equlibrium constant =
![\frac{[H_2]^2[O_2]}{[H_20]^2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5BH_2%5D%5E2%5BO_2%5D%7D%7B%5BH_20%5D%5E2%7D%20)
[ ] bracket in above expression indicates concentration.
Pretty sure its 1 but I may not be correct.
