Answer:
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The equation for the ionization of the silver chromate is given as:
We are given:
Solubility of = S mol/L
By stoichiometry of the reaction:
1 mole of gives 2 moles of and 1 mole of .
When the solubility of is S moles/liter, then the solubility of will be 2S moles\liter and solubility of will be S moles/liter.
Expression for the equilibrium constant of will be:
Hence, the solubility of is
Answer:
B, C
Explanation:
The atoms or ions with the valid Lewis dot structures are B and C.
In A;
The Lewis structure of the carbon is correct. Each of the four dots represent the four valence electrons.
The nitrogen with one dot on top, left and to the bottom and has a charge of minus 3 is wrong. For it to have a charge of -3 it must have 8 lewis dots ( two on the top, right, bottom and to the left)
The nitrogen with four dots (on top, right, bottom and to the left) is wrong.
In B;
An oxygen has two dots on top and bottom and one dot to the left and to the right. This is correct , the 6 dots represent the valence electrons of oxygen.
In C;
A carbon has two dots on top, right, bottom and to the left and a charge of plus four. This is correct because the charge indicates that it has gained four extra electrons so its valence electrons is now 8.
In D;
An oxygen has two dots on top, left and to the bottom and a charge of minus 2. This is wrong because the lewis dots are incomplete. Two dots are missing.
Sodium, potassium, strontium, calcium, and magnesium
Answer:
its c that is easy u welcome love
Explanation:
The rate of the forward reaction equals the rate of the reverse reaction.
<h3>What is dynamic equilibrium?</h3>
When it comes to chemical reactions, a dynamic equilibrium is a condition in which a reversible reaction produces products and reactants at an equal rate.
Dynamic equilibrium can only be achieved in a closed system. That is, a system in which there are no external influences in form of energy, material, or pressure.
For example, consider the following reversible reaction:
If the reaction is in dynamic equilibrium, there will not be a net production of reactants and products. In other words, the rate of production of A and B will be the same as the rate of production of C and D.
This is as opposed to static equilibrium in which the production of both reactants and products stops completely after reaching equilibrium.
