In the solvolysis of 2-chloro-2-methylpropane, di-t-butyl ether formation occurs as a byproduct due to the interaction between the carbocation intermediate and a solvent molecule.
This is because the solvent used in the reaction, typically ethanol or water, can act as a nucleophile and attack the carbocation intermediate formed during the reaction. The carbocation intermediate is a positively charged species that is formed when the leaving group, in this case, the chloride ion, leaves the molecule.
When the nucleophile attacks the carbocation intermediate, it can form different products depending on the conditions of the reaction.
In the case of the solvolysis of 2-chloro-2-methylpropane, the nucleophile can attack the carbocation intermediate at either the carbon atom bearing the methyl group or the carbon atom bearing the tert-butyl groups.
If the nucleophile attacks the carbon atom bearing the methyl group, a molecule of ethanol or water is eliminated, resulting in the formation of di-t-butyl ether as a byproduct.
The reaction sequence for the solvolysis of 2-chloro-2-methylpropane can be represented as follows:
Starting material: 2-chloro-2-methylpropane
2-chloro-2-methylpropane + solvent (ethanol/water) → carbocation intermediate + leaving group (Cl-)
Carbocation intermediate + nucleophile (solvent) → di-t-butyl ether + solvent (ethanol/water)
As shown below;
Step 1: (C-Cl bond cleavage) → Tertiary carbocation + Cl⁻
Step 2: (Reaction with alcohol) → Di-t-butyl ether
Overall reaction:
2-chloro-2-methylpropane + solvent (ethanol/water) → di-t-butyl ether + leaving group (Cl-) + solvent (ethanol/water)
This side reaction competes with the main solvolysis reaction, leading to the formation of di-t-butyl ether in addition to the expected products.

How can you prove that air is a matter ?
Answer:
One way to prove that air is made of matter is to blow up a balloon. Before you add air into the balloon, it is empty and shapeless. When you puff air into it, the balloon expands, so you know it is filled with something—air is taking up space. You'll also notice that a balloon filled with air sinks to the ground.

The pH of a solution is 8. Some hydrochloric acid is added to the solution. Suggest the pH of the solution after mixing. pH=.......??
Answer:
By adding acid to hydrogencarbonate you create a large concentration of CO2 in solution causing the solution to be highly supersaturated. This keeps the pH down as CO2 is in equilibrium with carbonic acid. During the day long mixing the excess CO2 strips off and as acid leaves the solution the pH increases.
Explanation:
Hope it helps
A solution with a pH of 8 will have its pH reduced with the addition of hydrochloric acid.
What is pH?It is the degree of acidity or alkalinity of solutions.
pH ranges from 0 to 14 with 7 being a neutral pH. Any pH below 7 is acidic while above 7 is basic.
Thus, a pH of 8 is basic and the addition of hydrochloric acid will reduce it towards 7 or even below it.

:
Answer:
Atom, cell, dust particle, ant, ping pong ball
Explanation:
Firstly, atoms make up all matter, including each of the items on that list. The only things smaller than atoms are the parts of the atom itself, protons, neutrons and electrons. Because none of those are on that list, atoms have to be the smallest. Next smallest is the cell. Cells are made up of atoms, but they also in part make up dust. You can see a dust particle with the naked eye, but in order to see a cell you must use a microscope. Thus, cells are smaller than dust particles. Next is an ant. Obviously, an ant is bigger than a speck of dust, and is made up of cells and atoms. Lastly all you have is the ping pong ball, which is much larger than the rest of the items. Hope this helps!
All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.
Thus, Atoms must be the tiniest object because none of those are included in that list. The cell is the next smallest. Atoms make up cells, but dust also makes up a portion of them.
A dust particle can be seen with the unaided eye, but a microscope is required to see a cell.
Cells are hence smaller than dust particles. An ant comes next. Of course, an ant is composed of cells and atoms and is larger than a particle of dust.
Thus, All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.

Answer:
Explanation:
Here's the complete question:
A chemist analyzes two samples.One sample contains 14g of element x and 6.0g of element y.The second sample contains 28g of element x and 6.0g of element y. Does it appear that the two samples are the same substance?
The two samples that we are given in the question are different. They are not the same thing because we can deduce that their components ratio are different.
Sample One contains 14g of element x and 6.0g of element y. The ratio of element x to y is 14/6 = 7/3 = 7:3.
Sample Two contains 28g of element x and 6.0g of element y. The ratio of element x to y is 28/6 = 14/3 = 14:3.
Therefore, they have different ratio for their components and are therefore not thesame.

Heavier noble gases are able to form compounds with other elements under specific conditions because their valence ____are farther from the _____
Answer:
Heavier noble gases are able to form compounds with other elements under specific conditions because their valence electrons are farther from the nucleus.
Explanation:
The name of noble or inert gas is due to the lack of reactivity with other elements. This is due to its electronic configuration, because its outermost shell or valence shell is always complete, without the need to share, give or receive electrons forming bonds. That is, its outer layer is so stable that the element tends not to react with others except in very specific cases.
These exceptions generally involve the heavier noble gases, such as xenon or radon, capable of forming compounds with fluorine and oxygen. This is because the heavier noble gases have more electron shells than the lighter ones. This characteristic causes the outermost electrons to experience a "shielding" effect due to the action of the inner electrons, and they can then be ionized more easily, since the attraction they receive from the positive charges of the nucleus is weaker. That makes the ionization energy low enough to form stable compounds with more electronegative elements, such as fluorine and oxygen.
Heavier noble gases are able to form compounds with other elements under specific conditions because their valence electrons are farther from the nucleus.

Fire ants move in to a new environment with the lizards.what will most likely happen to the lizard population over the next several years
Answer:
Some lizards in the eastern U.S. have adapted to invasive fire ants -- which can bite, sting, and kill lizards -- reversing geographical trends in behavioral and physical traits used to avoid predators. A new study describing this reversal appears online on November 29, 2018, in the journal Global Change Biology and reveals that new environmental challenges can override the historical influences that originally determined geographical trends in traits.
"Rapid environmental change, be it from changing climate or the introduction of invasive species, is putting a lot of pressure on native species," said Christopher Thawley, graduate student at Penn State at the time of the study and first author of the paper. "Usually when researchers look at how native species might respond to these kinds of threats, they might measure one characteristic of the animal and at one or a few sites. In this study, we looked at three separate characteristics of eastern fence lizards from thirteen sites spanning a thousand miles and found that these lizards are capable of adapting in a concerted way to meet the threat of invasive fire ants, and in a relatively short time frame."
