Answer:</h3>
The structure of Electrophile (2-methylpropan-2-ylium) is shown in attached picture highlighted by green color.
<h3>Explanation:</h3>
Electrophiles are those species which are electron deficient and loves electron. These species often carry positive charge or contain atoms which have incomplete octet.
Also, we know that Benzene undergo Electrophilic Substitution reactions in which hydrogen atom is replaced by other electrophile. In given statement the electrophile to be reacted with benzene to form tert-Butylbenzene is generated from 2-methylpropene. 2-methylpropene when treated with phosphoric acid adds one proton across the double bond (electrophilic addition reaction) and generate a positively charged tertiary carbocation (stable) (highlighted green) which acts as an electrophile. Further on reaction with benzene this electrophile is substituted with proton and results in the formation of tert-Butylbenzene.
When thermal energy is added, the motion of particles increases.
This can be thought of when thinking of a gas. We know that a gas includes particles that move fast and are spaced far apart from each other. On the opposite side of the spectrum, we know that a solid includes particles that are closely packed together with limited movement.
Using those examples, we know that a solid usually occurs at colder temperatures (with low thermal energy), and gases occur at warmer temperatures (with high thermal energy).
Therefore, when thermal energy is added, particle motion increases.
The amount of salt added to water does not affect the boiling point ot would stay at 100 degrees c or 212 degrees F
Explanation:
they are located in the neucleus
