[H₃O⁺] = 8.86 x 10³ M

<h3>Further explanation</h3>

The dissociation of water :

H₂O(l)⇒H⁺+OH⁻

Hydrogen ions H⁺ bond with H₂O to form H₃O⁺ ions(hydronium ion)

When acid(Hbr acid) is in the presence of water(dissociates), the H⁺ ions bond with water molecules to form hydronium, the reaction :

HBr(aq)+H₂O→H₃O+(aq)+Br−(aq

So Ionization of HBr :

\tt HBr\rightarrow H_3O^++Br^-

[HBr]= 8.86 x 10³,

From equation ratio [H₃O⁺] : HBr = 1 : 1, so

\tt [H_3O^+]=8.86\times 10^3

Answer:

6.68 X 10^-11

Explanation:

From the second Ka, you can calculate pKa = -log (Ka2) = 6.187

The pH at the second equivalence point (8.181) will be the average of pKa2  and pKa3. So,

8.181 = (6.187 + pKa3) / 2

Solving gives pKa3 = 10.175, and Ka3 = 10^-pKa3 = 6.68 X 10^-11

Answer:   Limiting reactant = 3  

                Theoretical Yield= 1

                  Excess reactant=2

Explanation:  The theoretical yield is the maximum possible mass of a product that can be made in a chemical reaction. It can be calculated from: the balanced chemical equation. the mass and relative formula mass of the limiting reactant , and. the relative formula mass of the product.

An excess reactant is a reactant present in an amount in excess of that required to combine with all of the limiting reactant. It follows that an excess reactant is one remaining in the reaction mixture once all the limiting reactant is consumed.

The limiting reagent is the reactant that is completely used up in a reaction, and thus determines when the reaction stops. From the reaction stoichiometry, the exact amount of reactant needed to react with another element can be calculated
