Answer:
Option A.
Explanation:
To know which structure is correct, let us name both compound.
In naming the above organic compound, the following must be observed:
1. Locate the functional group. In this case it alkene since it has carbon to carbon double bond (C=C).
2. Locate the longest continuous carbon chain. In this case the compound is a cyclic compound with 6 carbon i.e cyclohexene.
3. Locate the substituents attached to the compound. In this case, bromine (bromo) and chlorine (chloro) are the substituents attached.
4. Locate the position of the substituents and name alphabetically counting from the double bond. In this case, bromo comes before chloro
5. Combine the above to get the name.
For option A, the name is:
4–bromo–5–chlorocyclohexene.
For option B, the name is:
3–bromo–4–chlorocyclohexene.
We can see that Option A gives the correct structure of the compound.
I would say it’s option c.
I hope it helps and have a nice day : )
The common ion effect is the decreased solubility of the ionic precipitate in the solution. To promote the precipitation of the calcium sulfate, magnesium sulfate must be added.
<h3>What is the common ion effect?</h3>
It is a phenomenon that is due to the addition of the common ion already present in the solution that affects the equilibrium and is used to decrease the solubility of the solute present in the solution to increase the precipitation rate.
Magnesium sulfate will be added to the solution as it already contains the sulfate ion in the form of calcium sulfate. This will increase the precipitation of the compound as the common ion added will decrease the solubility.
Therefore, magnesium sulfate will be added to promote precipitation.

Answer:
33
Explanation:
The atomic number of an element configuration 2,8, 8,2,13 is 33.
The electron configuration is defined as the arrangement of electrons in atomic or molecular orbitals of an atom. The sum of electrons in different orbitals shown in the electron configuration represents the atomic number of the atom.
So, atomic number of the element configuration 2,8, 8,2,13 is 33.
Answer:
Removing O₂, means removing one of the reactants and the system would counteract this effect by producing more O₂, thereby shifting the equilibrium position to the left and favouring the backward reaction.
Explanation:
The principle that explains how changes in temperature, Concentration and Pressure of reactants or products of a reaction at equilibrium affect the equilibrium position of the reaction is the Le Chatelier's principle.
The Principle explains that a system/process if a system/process which is at equilibrium is disturbed/perturbed/constrained by one or more changes (in concentration, pressure or temperature), the system would shift the equilibrium position to counteract the effects of this change.
Removing O₂, means removing one of the reactants (changing its concentration) and the system would counteract this effect by producing more O₂, thereby shifting the equilibrium position to the left and favouring the backward reaction.
