Fluorine, Chlorine, Bromine, Iodine and Astatine are representing the family of elements called : halogens.
Halogens:
- all have 7 electrons in their outer shell,
- are very reactive elements,
- form - 1 ions.
Answer: C ) They have same chemical properties.
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 is "<span>the
oxidizing agent receives electrons from the reducing agent</span><span>".
There are two types of reactants in redox reactions. One is oxidizing agent and
other is reducing agent.
Oxidizing agent is a substance which helps to oxidize other substance by
gaining electrons. This is also called as oxidizer. Due to the gaining
electrons, oxidizing agents tend to be reduced.
Reducing agent or reducer helps to reduce other substance while loosening
electrons. Hence, reducing agents tend to be oxidized.</span>
