The maximum solubility of Ag₂CO₃ = = 1 x 10⁻⁵
<h3>Further explanation</h3>
Given
0.02 M Na₂CO₃
Ksp of Ag₂CO₃ is 8 x 10⁻¹²
Required
The solubility of Ag₂CO₃
Solution
Ag₂CO₃ ⇒ 2Ag⁺ + CO₃²⁻
s 2s s
s = solubility
Ksp Ag₂CO₃ = [Ag⁺]² [CO₃²⁻]
Ksp Ag₂CO₃ = (2s)².s
Ksp Ag₂CO₃ = 4s³
In 0.02 M Na₂CO₃ ⇒ 2Na⁺ + CO₃²⁻⇒ [ CO₃²⁻]=0.02, so Ksp Ag₂CO₃ :
8 x 10⁻¹² = [2s]² [0.02]
8 x 10⁻¹² = 4s² [0.02]
4s² = 8 x 10⁻¹² / 2 × 10⁻²
4s² = 4 x 10⁻¹⁰
s² = 1 x 10⁻¹⁰
s = √1 x 10⁻¹⁰
s = 1 x 10⁻⁵
Answer:
I would answer but thats a lot of work. I understand why you didnt do it yourself.
The correct matches are as follows:
1. Big Bang theory: Theory that suggests the origin of the universe started with an explosion and expansion of a very hot, dense, compact fireball.
2. Steady state theory: Theory about the origin of the universe that suggest that the universe has and will continue to be at a steady continuous state.
3. Oscillatory universe theory: Theory about the origin of the universe that suggests the universe is a never ending cycle of expansion and contraction.
4. Nebular theory: Theory about the origin of the solar system that suggest our sun and planet formed from a cloud of dust and gas.
5. Inflation theory: Theory that upholds the big bang theory but suggest there was an extremely rapid expansion or inflation milliseconds after the big bang.
6. Condensation theory: Theory about the origin of the solar system that agree with the nebular theory but stresses the importance of interstellar dust in planet formation.
Answer:
i would say A-B
