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:
The enzyme's active site must be the mold shape of the substrate.
Explanation:
An enzyme and a substrate bind together in order to work. If the shapes of the 2 are different, they will not be able to bond together. If the shapes of the 2 fit glove-in-hand, then they will be able to bond together.
Answer:
Deflategate was a National Football League (NFL) controversy involving the allegation that New England Patriots quarterback Tom Brady ordered the deliberate deflation of footballs used in the Patriots' victory against the Indianapolis Colts in the 2014 American Football Conference (AFC) Championship Game.

Answer:
32 g
Explanation:
molar masses of elements such as sulfur can be found on the periodic table.
the molar mass listed on the periodic table equals 1 mole of the atom which also equals 6.02×10^23
therefore, 32g = 1 mole of sulfur = 6.02×10^23
(1 mole always equals 6.02×10^23)
