Might be D bc it’s the only one that makes sense to me
PH=-log[ H₃O⁺] therefore [H₃O⁺]=10^-pH
[H₃O⁺]=10^-11
<span>[H₃O⁺]</span>=1.0x10^-11
Because Carbon has to make 4 bonds. However, it does makes 3 or 5 bonds in some cases. But, it is highly unstable under those conditions.
Hope this helps. :)
Answer:
0.200 M
Explanation:
Begin by finding how many moles of KCl there are by using the molarity and given volume:
(Remember that molarity is mol/L, which is equal to mol/1000 mL.)
Next, divide the moles of KCl by the new volume (after dilution):
The new concentration is 0.200 M.
