Which statement is true for all minerals

Matter can exist as a solid, a liquid, or a gas. The solid state is distinguished by its ability to

Elina [12.6K]

Answer:

D

Explanation:

A solid is characterized by structural rigidity and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas. Solids molecules stay close to eachother maintaining its shape meaning it is in a ordered pattern.

Suppose the plates beneath Earth's surface stopped moving.What do you think would happen?Explain your answer.

Amanda [17]

There would be no more earthquakes or volcanic eruptions as the earth's plate are the cause of both these occurrences.(which can be seen as a positive)
However, the plates allow the earth to cool when they move because they cause heat loss.If the plates were to stop moving the earth would have to loose heat another way and since we cant tell how this would happen, it could be very dangerous.

Predict the two most likely mechanisms for the reaction of 1-iodohexane with potassium tert-butoxide.

Rudiy27

Answer:

C) SN2 and E2

Explanation:

For this question, we have analyzed the substrate and the base/nucleophile. The substrate, in this case, is 1-iodohexane and the base/nucleophile is potassium tert-butoxide.

Substrate

In the 1-iodohexane the iodide "I" is bonded to a primary carbon (carbon 1). Therefore we will have a primary substrate. If we have a primary substrate an Sn1 can not take place. We can not have a primary carbocation due to this instability. So, we can disccard options A) and B).

Base/nucleophile

In the potassium tert-butoxide we have an ionic compound. A positive charge is placed in the potassium atom a negative charge is placed in the oxygen of the ter-butoxide ion. So, we will have a strong base (a molecule with the ability to remove electrons) and a strong nucleophile (a molecule with ability to bond with an electrophile). With all this in mind, we can not have an E1 reaction.

With both analyses, the answer is C).

See figure 1

I hope it helps!
