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!
The most stable configuration for Cu (copper) would be 1s2 2s2 2p6 3s2 3p6 4s2 3d9 for the noble gas configuration would be (Ar) 4s2 3d9.
Generally, a liquid freezes exothermally on cooling and a crystal melts endothermally on heating.
The 6 phase changes are vaporization, condensation, freezing, melting, sublimation, and deposition
Answer:
One orientation
Explanation:
A s orbital is a sphere like shape that surrounds the atomic nucleus that consists of electrons that can be found at the highest or lowest region of the orbital. S orbitals only consist of "one orientation" and is commonly mistaken by the p orbital because the p orbital also consists of electrons that can be found the most.
Hope this helps.
