pH = 9.5
Explanation:
We know that the hydronium ion concentration is [H₃O⁺] = 3.16 × 10⁻⁹ M.
The formula for pH is:
pH = -lg[H₃O⁺]
We input the known values to find the pH:
pH = -lg[3.16 × 10⁻⁹]
pH = 9.5

Answer:
Double replacement:
Explanation:
Chemical equation:
2AsCl + 3H₂S → As₂S₃ + 6HCl
The given reaction is double displacement reaction. In this reaction arsenic trichloride and hydrogen sulfide react and produced arsenic sulfide and hydrogen chloride. In double displacement reaction both anion an cation of reactants are exchanged with each other.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
General equation:
AB + CD → AD +CB
0 plus 5 negative and accumulated
It has many different uses like being used to make the tube of a vacuum cleaner and also can be used to make oil in space crafts.
