Answer:
A I believe is your best choice.
Explanation:
We calculate the molar concentration [Cl⁻] using stoichiometry. MnCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MnCl2 that dissolves.
MnCl2(s) --> Mn+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.68 mol MnCl2/1L × 2 mol Cl⁻ / 1 mol MnCl2 = 1.4 M
The answer to this question is [Cl⁻] = 1.4 M

I took a test and got this question right
Answer:
Acid.
Explanation:
I assume you mean 4.5?
pH below 7 is acidic
pH above 7 is alkaline
pH equal to 7 is neutral
4.5 lies below 7, so it is acidic
There are 3 atoms found in one molecules of
