Answer:
The five assumption of Kinetic molecular theory are given below.
Explanation:
Kinetic molecular theory of gasses stated that,
1) Gases consist of large number of smaller particles which are distance apart from each others.
2) The gas molecules collide with each other and also with wall of container and this collision is elastic.
3) Gas molecules are in continuous random motion and posses kinetic energy.
4) The forces of attraction between gas molecules are very small and considered negligible.
5) The temperature of gas is directly proportional to average kinetic energy of gas molecules.
Answer is: Ksp for calcium sulfate is 2.36·10⁻⁴.
Balanced chemical reaction (dissociation):
CaSO₄(s) → Ba²⁺(aq) + SO₄²⁻(aq).
m(CaSO₄) = 0.209 g.
n(CaSO₄) = m(CaSO₄) ÷ M(CaSO₄).
n(CaSO₄) = 0.209 g ÷ 136.14 g/mol.
n(CaSO₄) = 0.00153 mol.
s(CaSO₄) = n(CaSO₄) ÷ V(CaSO₄).
s(CaSO₄) = 0.00153 mol ÷ 0.1 L = 0.0153 M.
Ksp = [Ca²⁺] · [SO₄²⁻].
[Ca²⁺] = [SO₄²⁻] = s(CaSO₄).
Ksp = (0.0153 M)² = 2.36·10⁻⁴.
