Answer:
a) 2-chloro-2,3-dimethylbutane
b) 1-chloro-2,3-dimethylbutane
Explanation:
The <u>monochlorination</u> is a reaction in which we have to add <u>only 1 Cl</u> to the molecule. In this case, we will have to add a Cl to a <u>primary carbon</u> (a) and to a <u>tertiary carbon</u> (b).
In the monochlorination of the primary carbon, we can choose any <u>methyl carbon</u>. For the monochlorination of the terciary carbon we have to choose an <u>CH carbon</u>.
(See the figure)
He. it is a noble gas and therefore has a full outer shell of electrons. it does not need to gain or loose any.
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.

Answer:
D. The data supported the hypothesis
Explanation:
The data shows that rats fed a normal diet with the addition of vitamins gained a higher average weight gain in the period of 3 months, compared to rats fed a normal diet. This supports the scientists' hypothesis of "Young rats that had vitamins added to their food would gain weight faster than young rats fed a normal diet."
