Evaporation is the process shown above
Hello!
datos: Molarity = 
ps: The ionization constant of the sulfuric acid is strong and completely dissociates in water, so the pH will be:
![pH = - log\:[H_3O^+]](https://tex.z-dn.net/?f=%20pH%20%3D%20-%20log%5C%3A%5BH_3O%5E%2B%5D%20)
![pH = - log\:[1*10^{-4}]](https://tex.z-dn.net/?f=%20pH%20%3D%20-%20log%5C%3A%5B1%2A10%5E%7B-4%7D%5D%20)



Note:. The pH <7, then we have an acidic solution.
I Hope this helps, greetings ... DexteR!
Answer:
In the given case, the atomic number of the given atom is 15, hence its nucleus contains 15 protons. The number of protons and electrons are the same in atom and that is what keeps it neutral. In the second case, the atomic number is 20. Hence, the atom will contain a total of 20 protons in its nucleus.
Explanation:
It has mass and takes up space is correct.
Answer:
Test for sulphate ion present in a given salt: Add barium chloride solution. If white precipitate is formed, presence of SO42- ion is confirmed.
