Most elements tend to have the same number of electrons and protons. This gives the element a neutral charge, aka no charge at all.
Here is an example:- Flourine
7 electrons and 7 protons
Electrolyte is any species which when dissolved in solvent particularly water dissociates into cations and anions. Electrolytes are conductors of electricity. In given options;
CCl₄ (Tetrachloromethane) is a covalent compound. And it doesn't dissociate to any cation or anion. So it is not electrolyte.
SiO₂ (Silicon Dioxide) is also covalent in nature and exist in giant framework. It is not electrolyte.
Glucose (C₆H₁₂O₆) is also covalent compound. And doesn't produced any ion in water, hence it is not electrolyte.
H₂SO₄ (Sulfuric acid) is Electrolyte. When it is dissolved in water it produces H⁺ and SO₄²⁻ ions as follow,
H₂SO₄ → 2 H⁺ ₍aq₎ + SO₄²⁻ ₍aq₎
Result:
H₂SO₄ is electrolyte.
<u>Answer:</u> The 
of the acid is 6.09
<u>Explanation:</u>
For the given chemical reaction:
The expression of equilibrium constant [tex[(K_a)[/tex] for the above equation follows:
![K_a=\frac{[H^+][A^-]}{[HA]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BH%5E%2B%5D%5BA%5E-%5D%7D%7B%5BHA%5D%7D)
We are given:
![[HA]_{eq}=0.200M](https://tex.z-dn.net/?f=%5BHA%5D_%7Beq%7D%3D0.200M)
![[H^+]_{eq}=4.00\times 10^{-4}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D_%7Beq%7D%3D4.00%5Ctimes%2010%5E%7B-4%7DM)
![[A^-]_{eq}=4.00\times 10^{-4}M](https://tex.z-dn.net/?f=%5BA%5E-%5D_%7Beq%7D%3D4.00%5Ctimes%2010%5E%7B-4%7DM)
Putting values in above expression, we get:
p-function is defined as the negative logarithm of any concentration.
So,
Hence, the of the acid is 6.09
I believe each oxygen shares 2 elections with the other.
Some material from meteors lingers in the mesosphere, causing this layer to have a relatively high concentration of iron and other metal atoms. Very strange, high altitude clouds called "noctilucent clouds" or "polar mesospheric clouds" sometime form in the mesosphere near the poles.
I really hope this helps! I wish you the best of luck!
