Answer: The formula of the acid that was neutralized is 
Explanation:
Neutralization is a chemical reaction in which acid and base combine to form salt and water. Acids donate 
and bases donate 
in water which combine to form water molecules.
As the salt formed is 
, the acid must contain 
and thus the acid is
The balanced chemical reaction is ;
The formula of the acid that was neutralized is
The first half reaction is:
Sn+ -> Sn2+
You add 1 electron on the right side:
Sn+ -> Sn2+ + 1e-
The second half reacation is:
Ag+ -> Ag
You add 1 electron to the left side:
Ag+ + 1e- -> Ag
Then, you combine both reactions to get the balanced overall reaction since both half reactions have 1 electrons on the right and left side, respectively. You get:
Sn+ + Ag+ -> Sn2+ + Ag

Explanation:
The given reaction is as follows.
Initial : 0.160 0.160 0
Change : -x -x 2x
Equilibrium: 0.160 - x 0.160 - x x
It is given that ![[H_{2}]](https://tex.z-dn.net/?f=%5BH_%7B2%7D%5D)
= [0.160 - x] = 0.036 M
and, ![[I_{2}]](https://tex.z-dn.net/?f=%5BI_%7B2%7D%5D)
= [0.160 - x] = 0.036 M
so, x = (0.160 - 0.036) M
= 0.124 M
As, [HI] = 2x.
So, [HI] = 
= 0.248 M
As it is known that expression for equilibrium constant is as follows.
![K_{eq} = \frac{[HI]^{2}}{[H_{2}][I_{2}]}](https://tex.z-dn.net/?f=K_%7Beq%7D%20%3D%20%5Cfrac%7B%5BHI%5D%5E%7B2%7D%7D%7B%5BH_%7B2%7D%5D%5BI_%7B2%7D%5D%7D)
= 
= 47.46
Thus, we can conclude that the equilibrium constant, Kc, for the given reaction is 47.46.
Answer:
<em>Mass number = protons + neutron</em>
<em />
<em>The mass number of an element is the sum of the protons and neutrons. The number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the number of protons).
</em>
<em>
</em>
<em>In this case the mass number would be 11</em>
