1.199 M is the concentration of KCI in the resulting solution.
<h3 /><h3>What are moles?</h3>
A mole is defined as 6.02214076 × 
of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
No.of moles of KCI
= 0.599 moles
Vol.of the solution,V= 500 ml
= 0.5 liter
Molarity
= 1.199 M
Hence, 1.199 M is the concentration of KCI in the resulting solution.

Answer:
All the above
Explanation:
A. Electrical current conduction
Aqueous solutions of both strong and weak acids will conduct an electric current. Weak acids are poorer conductors because they produce fewer ions.
B. Reaction with magnesium
Both strong and weak acids will react with magnesium, although weak acids will react more slowly.
C. pH paper test
Both strong and weak acids will give a colour with pH test paper, although the colours will probably be different.
D. Litmus paper test
Both strong and weak acids will turn blue litmus red.
The first one is the 2Hg+.....
The second is the Ca+ 2H2O....
The third is the first one, H2 + Cl2...
And the last is Fe+ S= FeS
It was so easy
Good Luck
