Answer:
a) 0.2118 mol of I₂ is produced.
b) 49.93 g of I₂ is produced.
Explanation:
a) The balanced equation shows that to produce 1 mol of I₂ we need 2 mol of CuCl₂ . Therefore, the amount of I₂ produced will always be half the amount of CuCl₂ given.
b) In order to calculate the mass of I₂ produced we need to know its molar mass:
Each mole of I₂ weighs 253.8 g, therefore MM = 253.8 g/mol.
The solubilty product (Ksp) of PbCl₂ : Ksp = [Pb²⁺][Cl⁻]²
<h3>Further explanation</h3>
Given
PbCl₂ compound
Required
The solubilty product (Ksp)
Solution
Ksp is the product of ions in an equilibrium saturated state
For reaction :
AₓBₐ (s) ⇔ aAᵃ⁺ (aq) + b Bᵇ⁻ (aq)
Can be formulated :
Ksp = [Aᵃ⁺] ᵃ [Bᵇ⁻] ᵇ
For PbCl₂ :
PbCl₂(s)⇔Pb²⁺(aq) + 2Cl⁻(aq)
Ksp = [Pb²⁺][Cl⁻]²
Answer:
6 N
Explanation:
Force (Newtons) = mass (kg) times acceleration (m/s2)
2 kg x 3m/s2 = 6 kg/m/s2
