Answer: It can be further reduced or diluted

Explanation:

Solvent is a solution and breaks the material down so the more you add the more it dissolves

11. a. Amphoteric

12. a. NH₄⁺, H₂O

Explanation:

11. A substance that can act as either an acid or a base is said to be amphoteric.

Water is an amphoteric substance because it can reaction with either and acid or a base.

HCl + H₂O → Cl⁻ + H₃O⁺

NH₃ + H₂O → NH₄⁺ + OH⁻

12. What are the acids in the following equilibrium reaction?

NH₃ (aq) + H₂O (l) → NH₄⁺ (aq) +OH⁻ (aq)

H₂O water is acid 1

NH₄⁺ ammonium ion is acid 2

Snowcat [4.5K]

Answer:

Yes.

Explanation:

Yes, I think that Barcelona has large temperature changes throughout the year because Barcelona has minimum temperature of 33°F in winter season and maximum temperature of 88°F in summer season. In Barcelona, the summers are short, warm, and humid while on the other hand, the winters in Barcelona are long, cold, and partly cloudy. The temperature typically varies from 40°F to 83°F and is rarely goes below 33°F or above 88°F.

There are two stereoisomers of 1-tert-butyl-4-chloro-cyclohexane. One of these isomers reacts with sodium ethoxide in an E2 reac

Naily [24]

Answer:

Explanation:

Answer:

cis-isomer reacts faster

Explanation:

The missing diagrams in the question are attached in the first image below and the isomers that react faster are shown in the second image attached.

The cis-isomer quickly follows E2 reaction due to the fact that it is locked in a chair conformation whereby chlorine dominates an axial position, as displayed in drawing C as well as the leaving group Cl which is antiperiplanar to a beta proton.

Due to the bulkiness of tert-butyl, the trans-isomer is Basically trapped in a chair configuration, with chlorine occupying an equatorial position as displayed in drawing A below, thus leaving the group isn't antiperiplanar to a beta proton.

Tert butyl favors an equatorial position due to its bulkiness. This makes the Cl to assume an axial position in an isomer

The difference:

From the second image attached below, in the first diagram(1):

Suppose H is antiperiplanar, C-H bond electrons reach antibonding orbitals of C-Cl, assisting in the breakdown of the C-Cl bond and therefore speeding up the process.

From the second diagram(2) in the second image:

Unless Cl is in the axial position would it have β-hydrogen in the antiperiplanar position. Because tert-butyl prefers equatorial location, the Cl occupies equatorial position in the trans isomer.

As a result, the reaction is slower and there is no β-hydrogen antiperiplanar to Cl.
