<u>Answer:</u> The pH of the solution is 1.41
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
Given mass of perchloric acid = 581.1 mg = 0.5811 g (Conversion factor: 1 g = 1000 mg)
Molar mass of perchloric acid = 100.5 g/mol
Volume of solution = 150 mL
Putting values in above equation, we get:
1 mole of perchloric acid produces 1 mole of 
ions and 1 mole of 
ions
To calculate the pH of the solution, we use the equation:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
We are given:
![[H^+]=0.0385M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.0385M)
Putting values in above equation, we get:
Hence, the pH of the solution is 1.41
is the symbol of the species with 23 protons and 21 electrons.
Hence, option F is correct.
<h3>What is a proton?</h3>
Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge.
If it has 23 protons, then its proton number (also know as its atomic number) is 23. You can look that symbol up in your periodic table.
If it has 21 electrons then it has a net charge of 23(+) - 21. So we know the ionisation state of the species, and we can record that as a superscript after the symbol for the species.
Hence, is the symbol of the species with 23 protons and 21 electrons.

You will need the Gas Law:
pV = nRT
Since T and p are constant, R is constant too, then moles increases->volume will increase with the same ratio too!
Answer:
Explanation:
The valency of chlorine is 1 .It means that chlorine has seven valence electrons in its valence shell so it gains one electron from others to be stable during chemical reaction. so its valency is 1.
