Soil forms from weathered rocks and organic materials. Fertile soil depends on when and how it is used.
<h2>
Answer:C</h2>
Explanation:
A chemical equation is a equation that describes a corresponding chemical reaction.
A chemical reaction is generally written as
→
refer to all the reactants involved in the chemical reaction.
Reactants are usually written on the left hand side of the chemical equation.
refer to all the products formed in the chemical reaction.
products are usually written on the right hand side of the chemical equation.
In the given reaction,
,
are written on the right side of the equation.
So,, are the products.
It is a mixture. it can easily be separated.
Answer:
2Ag⁺ (aq) + CrO₄⁻² (aq) ⇄ Ag₂CrO₄ (s) ↓
Ksp = [2s]² . [s] → 4s³
Explanation:
Ag₂CrO₄ → 2Ag⁺ + CrO₄⁻²
Chromate silver is a ionic salt that can be dissociated. When we have a mixture of both ions, we can produce the salt which is a precipitated.
2Ag⁺ (aq) + CrO₄⁻² (aq) ⇄ Ag₂CrO₄ (s) ↓ Ksp
That's the expression for the precipitation equilibrium.
To determine the solubility product expression, we work with the Ksp
Ag₂CrO₄ (s) ⇄ 2Ag⁺ (aq) + CrO₄⁻² (aq) Ksp
2 s s
Look the stoichiometry is 1:2, between the salt and the silver.
Ksp = [2s]² . [s] → 4s³
