Answer:
Answer is attached but read below for full explanation.
Explanation:
This reaction is called Hydrolysis of Amides. Amides are carboxylic acid derivatives where the -OH of the carboxylic acid has been replaced by -NH2, -NHR, or -NR2 of an amine. Since the reaction between a carboxylic acid and an amine to give an amide also liberates water, this is an example of a "condensation reaction".
Answer is: the molarity of the solution is 0.0936 M.
Balanced chemical reaction: BaCl₂(aq) + Na₂SO₄(aq) → BaSO₄(s) + 2NaCl(aq).
Net ionic reaction: Ba²⁺ + SO₄²⁻ → BaSO₄(s).
V(BaCl₂) = 55.8 mL; volume of barium chloride solution.
V(BaCl₂) = 55.8 mL ÷ 1000 mL/L = 0.0558 L.
m(Na₂SO₄) = 742 mg ÷ 1000 mg/g.
m(Na₂SO₄) = 0.742 g; mass of sodium sulfate.
n(Na₂SO₄) = m(Na₂SO₄) ÷ M(Na₂SO₄).
n(Na₂SO₄) = 0.742 g ÷ 142.04 g/mol.
n(Na₂SO₄) = 0.00522 mol; amount of substance.
From chemical reaction: n(Na₂SO₄) : n(BaCl₂) = 1 : 1.
n(BaCl₂) = 0.00522 mol.
c(BaCl₂) = n(BaCl₂) ÷ V(BaCl₂).
c(BaCl₂) = 0.00522 mol ÷ 0.0558 L.
c(BaCl₂) = 0.0936 M.
Explanation:
Volume is the quantity of three-dimensional

<span>HCl(aq)+CH3NO2(aq)⇄CH3NH3+(aq)+CL-(aq)
Given that the concentrations of the HCl and methyamine are equal, so at the equivalence point the volume is doubled. The resulting concentration of CH3NH3+ is 0.095M
CH3NH3+(aq)⇄H+(aq)+CH3NH2(aq)
I 0.095 0 0
C -x +x +x
E 0.095-x x x
Ka=x^2/0.095-x
Ka=1.0x10^-14/5.0x10^-4
=2.0x10^-11
x^2/0.095-x=2.0x10^-11
x=1.38x10^-6
pH=-log(1.38x10^-6)
