Hello!
datos:
Molarity = ![2.0*10^{-4}\:M\:(mol/L)](https://tex.z-dn.net/?f=%202.0%2A10%5E%7B-4%7D%5C%3AM%5C%3A%28mol%2FL%29%20)
ps: The ionization constant of the nitric acid is strong (100% ionized in water) or 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\:[2*10^{-4}]](https://tex.z-dn.net/?f=%20pH%20%3D%20-%20log%5C%3A%5B2%2A10%5E%7B-4%7D%5D%20)
![pH = 4 - log\:2](https://tex.z-dn.net/?f=%20pH%20%3D%204%20-%20log%5C%3A2%20)
![pH = 4 - 0.30](https://tex.z-dn.net/?f=%20pH%20%3D%204%20-%200.30%20)
![\boxed{\boxed{pH = 3.70}}\end{array}}\qquad\checkmark](https://tex.z-dn.net/?f=%20%5Cboxed%7B%5Cboxed%7BpH%20%3D%203.70%7D%7D%5Cend%7Barray%7D%7D%5Cqquad%5Ccheckmark%20)
Note:. The pH <7, then we have an acidic solution.
I Hope this helps, greetings ... DexteR!
Explanation:
because in the right side there is 2 hydrogen( H) and 2 chloride (Cl) to balace them we have to replace 2.
Answer:
b. transfer of electron(s).
Explanation:
An oxidation-reduction also called a redox reaction is a
chemical reaction in which electrons are transferred of between two species of reactants. It is a chemical reaction where the oxidation number of an atom, ion, or molecule, increases or decreases by losing or gaining electrons
Idk it’s making me answer a question in order to get help on my own
