<h2>"resonance" refers to the idea that molecules are resonating rapidly between different bonding patterns. </h2>
Explanation:
This is the statement that defines resonance phenomenon.
In chemistry, resonance refers to some way of describing certain bonds, with the construction of resonance structures. This definition is often used to explain delocalised electrons that cannot be explained with covalent bonds.
Answer:
[OH-] for this solution is 4.255*10^-12
Explanation:
We are given
[H+] = 2.35 × 10-3 M
we need to find the concentration of [OH-]
we know from Equilibrium
[H+][OH-] = 10^-14
[OH-] = 10^14/2.35*10^10^-3
[OH-] = 0.4255*10^-11
[OH] = 4.255*10^-12
Therefore the Concentration of [OH-] for this solution is 4.255*10^-12
The answer is acidic.
pH < 7 = acidic
pH > 7 base
