BaSO₄(s) ⇄ Ba²⁺(aq) + SO₄²⁻(aq)

Ksp=[Ba²⁺][SO₄²⁻]

[Ba²⁺]=[SO₄²⁻]

Ksp=[Ba²⁺]²

Ksp=(1.76*10⁻³)² =3.0976×10⁻⁶ ≈3.1×10⁻⁶

Answer:

The value of solubility product of barium sulfate is 3.09\times 10^{-6}.

Explanation:

BaSO_4\rightarrow Ba^{2+}+SO_4^{2-}

                         S         S

1 mole of barium sulfate dissociates into 1 mole of barium ion and one mole sulfate ion.

So, [Ba^{2+}]=[SO_4^{2-}]=S

[Ba^{2+}]=S=1.76\times 10^{-3} M

The solubility product the barium sulfate will be given by:

K_{sp}=S\times S=S^2

K_{sp}= (1.76\times 10^{-3})^2=3.09\times 10^{-6}

The value of solubility product of barium sulfate is 3.09\times 10^{-6}.

The answer would be "false" or the second option. A opinion is what you think on a certain subject and science is full of facts and opinions of other scientist which would mean your using someone else for your opinion just remember opinions is what you think about a subject and you can't use science for your opinion.

Hope this helps!

SOVA2 [1]

initial volume of the argon sample = 5.93L according to Boyle's law

What is Boyle's law ?

Boyle's law, also known as Mariotte's law, is a relationship describing how a gas will compress and expand at a constant temperature. The pressure (p) of a given quantity of gas changes inversely with its volume (v) at constant temperature, according to this empirical connection, which was established by the physicist Robert Boyle in 1662. In equation form, this means that pv = k, a constant.

According to Boyle's law

P1/V1 = P2/V2

P1 = initial pressure

P2 = final pressure

V1 =initial volume

V2= final volume

V1 = P1*V2/P2

V1 = 2.32*18.3/7.16 = 5.93L

initial volume of the argon sample = 5.93L according to Boyle's law
