Answer:
He is most well known for discovering the role Oxygen plays in combustion
Explanation:
Answer:
Here you go.
Explanation:
First of all, there are reactants and products…
Reactants are in the left side (in bold).
Products are on the right (without bold)
Example; NH3 + O2 → N2 + H2O
As mentioned above, phosphoric acid has 3 pKa values, and after 3 ionization it gives 3 types of ions at different pKa values:
H₃PO₄(aq)
+ H₂O(l) ⇌ H₃O⁺(aq) + H₂PO₄⁻ (aq) pKₐ₁

</span>H₂PO₄⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + HPO₄²⁻ (aq) pKₐ₂
HPO₄²⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + PO₄³⁻ (aq) pKₐ₃
At the highest pKa value (12.4) of phosphoric acid, the last OH group will lose its hydrogen. On the picture I attached, it is shown required protonated form of phosphoric acid before reaction whose pKa value is 12.4.
HCI is one of the most common acids out of the following
The answer is A. Permeability.
