fish give off the compound ammonia which has a PH above 7. To which class of compounds does ammonia belong?
2 answers:
<u>Answer:</u> Ammonia is considered as a base.
<u>Explanation:</u>
pH is defined as the negative logarithm of hydrogen or hydronium ion concentration that are present in a solution.
The equation representing pH of the solution follows:
pH range of the solution varies from 0 to 14.
There are 3 types of solution: acidic, basic and neutral
- If the pH of the solution is from 0 to 6.9, the solution is said to be acidic.
- If the pH of the solution is from 7.1 to 14, the solution is said to be basic.
- If the pH of the solution is 7, the solution is said to be neutral.
We are given:
Ammonia has a pH above 7. So, this compound is a basic compound.
Hence, ammonia is considered as a base.

This problem is providing us with the chemical equation depicting the production of ammonia from nitrogen and hydrogen at equilibrium and asks for the correct change when the concentration of nitrogen is increased. At the end, the answer is the forward reaction would increase to start reducing the concentration of N2.
<h3>Chemical equilibrium</h3>In chemistry, chemical reactions not always reach a 100-% conversion when reactants get in contact in order to carry out the chemical reaction. Thus, there is a point wherein the concentrations remain the same and is called equilibrium.
In such a way, for this problem, we have the following chemical reaction at equilibrium:
Now, according to the Le Ch.atelier's principle, an increase in the concentration of any species, shifts the equilibrium away from it, which means that if we increase the concentration of nitrogen, a reactant, the forward reaction will be favored.
Thereby, the correct answer is "the forward reaction would increase to start reducing the concentration of N2".

Valence electrons are the electrons that are in an atom's outermost layer.
Every atom is made of protons, neutrons, and electrons.
Electrons are outside them both.
They have energy levels (number of electrons per layer)
And the number they have on the farthest layer are the valence electrons.
