Answer:
The solution is 10^-2 or 0.01M in HCl.
Explanation:
meaning of pH is "power of hydrogen".
what is the molar concentration of a HCl solution with pH=2?
Let say pH=2
[H+]=10^-2M
HCL is a strong acid that dissociates completely:
[H+]=[HCL]
Therefore solution is 10^-2 or 0.01M in HCL.
The answer is Ga.
That is gallium (Ga), correctly names the element that Mendeleev predicted would be discovered and placed in the aluminum column.
Gallium (Ga) is the element that Mendeleev predicted would be discovered and placed in the aluminum column.
So the answer is Gallium (Ga) that is there in the 13th group of periodic table or in aluminium column.
