The object that I think has potential energy within the images posted is the skateboard at the top of the ramp.
<h3>Why do i think this one has potential energy?</h3>
Potential energy is a type of mechanical energy in which there is a type of stored energy that can be transformed into another type of energy. This energy is given by the <u>location of the body</u> with respect to a force field.
I selected the image of the skateboard at the top of the ramp since going up there uses kinetic energy and when it is on top of the ramp, waiting to go down, this kinetic energy is stored in potential energy that is ready to be released. The higher the height at which it is launched, <u>the more its potential energy will be</u>.
Therefore, we can confirm that the object that I think has potential energy within the images posted is the skateboard at the top of the ramp.

decrease the free energy.
Answer:The product formed on reaction with hydroxide ion as nucleophile is 2R-hexane-2-ol.
The product formed on reaction with water would be a 50:50 mixture of
2S-hexane-2-ol. and 2R-hexane-2-ol.
Explanation:
2S-iodohexane on reactiong with hydroxide ion would undergo SN² substitution reaction that is substitution bimolecular. Hydroxide ion has a negative charge and hence it is a quite good nucleophile .
The rate of a SN² reaction depends on both the substrate and nucleophile . Here the substrate is a secondary carbon center having Iodine as a leaving group.SN² reaction takes place here as hydroxide ion is a good nucleophile and it can attack the secondary carbon center from the back side leading to the formation of 2R-hexane-2-ol.
In a SN² reaction since the the nucleophile attacks from the back-side so the product formation takes place with the inversion of configuration.
When the same substrate S-2-iodohexane undergoes a substitution reaction with water as a nucleophile then the reaction occurs through (SN¹) substitution nucleophilic unimolecular mechanism .
The rate of a SN¹ reaction depends only on the nature of substrate and is independent of the nature of nucleophile.
The SN¹ reaction is a 2 step reaction , in the first step leaving group leaves leading to the formation of a carbocation and once the carbocation is formed then any weaker nucleophile or even solvent molecules can attack leading the formation of products.
In this case a secondary carbocation would be generated in the first step and then water will attack this carbocation to form the product in the second step.
The product formed on using water as a nucleophile would be a racemic mixture of R and S isomers of hexane -2-ol in 50:50 ratio. The two products formed would be 2R-hexane-2-ol and 2S-hexane-2-ol.

Answer:
option C = all elements are balanced
Explanation:
In given chemical equation all elements are balanced.
Chemical equation:
MgO + 2LiCl → MgCl₂ + Li₂O
This is balanced chemical equation. We can see that there are one Mg atom and one oxygen atom is present in reactant side and also in product side. So, both are balanced.
In case of lithium there are two Li atoms in reactant side and also in product side , it is also balanced.
There are two chlorine atoms are present in reactant side and also in product side. Chlorine atoms are balanced.
