Answer:
The acid dissociation constant, _Ka__, is a quantitative measure of acid strength
Explanation:
Answer: both numbers are 2
Explanation:
The characteristic of reactions that depends on valence electrons is the bond type.
In chemistry, a chemical bond could be;
The type of bond formed depends on the number of valence electrons present. When there are few valence electrons on an atom, it mostly forms ionic bonds.
When there are more electrons on an atoms, it mostly forms covalent bonds and the electrons between the atoms are shared.

The concentration of the HCL in the mixed solution is 32%
Considering the First solution containing HCl,
80 ml of 50% = 80 x (50/100)
= 80 x 0.5
= 40 ml of HCL
Considering the second solution containing HCl,
120 ml of 80% = 120 x (20/100)
= 120 x 0.2
= 24 ml of HCl
So, the combined solution will have = 40+ 24
= 64 ml of HCL
Since the combined volume of the two solutions was = 80+120
= 200 ml
As for finding the concentration of HCl in a solution, the required formula is to divide the volume of HCl by the combined volution of the solution.
Therefore, the concentration of HCl will be = 64/200
= 0.32
Which is 32% of HCl
