How does the polarity of the solute affect how well a solvent will dissolve?

1 answer:

4 0

Polarity is the ability to distinguish between the electric charge of a molecule or different chemical groups having dipoles or multipole moment. Polar molecules have polar bonds based on the difference in electronegativity between atoms bonded together. Polarity affects how solvents dissolve by following the idea that "like dissolves like" in other words, polar molecules are best dissolved in polar solvents and nonpolar molecules dissolve better in nonpolar solvents. Moreover, ionic solvents dissolve polar solutes. By this the final answer is E, similar polarity makes the solvent more likely to dissolve

What is the speed of light?can a object move in speed of light?

timurjin [86]

Answer:

The speed of light is the speed at which light travels. No, an object cannot move at the speed of light.

Explanation:

The speed of light is 186,000 miles per second. An object with mass cannot move at the speed of light since it would take an infinite amount of energy to achieve that velocity, since only massless particles can travel at the speed of light. Also, you would have to factor in air friction, meaning even if an object were to reach such high speeds, it would instantly disintegrate.

Classify each of the four compounds as a conjugated, isolated, or cumulated diene. Compound A: Two alkenes are joined by a sigma

Lina20 [59]

Explanation:

Conjugated diene is the one that contains alternate double bonds in its structure. That means both the double bonds are separated by a single bond.

Cumulated diene is the one that contains two double bonds on a single atom. This means it has two double bonds continuously.

Isolated double-bonded compound has a single bond isolated by two to three single bonds.

Compound A: Two alkenes are joined by a sigma bond.

For example:

$-CH_2=CH-CH=CH2-$

It is a conjugated diene.

Compound B: Two alkenes are joined by a C H 2 group.

It is a cumulative diene.

Compound C: Two alkenes are joined by C H 2 C H 2.

Then it is an isolated alkene.

Compound D: A cyclohexene has a double bond between carbons 1 and 2. Carbon 3 is an sp 2 carbon that is bonded to another s p 2 carbon with an alkyl substituent.

Hence, compound D is a conjugated diene.

Which row in the table shows how many electrons there could be in the outer shell of an atom of V?

Amanda [17]

Answer:

Explanation:

The element V forms acidic oxide so it must be non- metal because oxides of non metal forms acidic oxide like sulphur ( s ) or chlorine ( Cl₂ )

sulphur forms SO₂ or SO₃ . Chlorine forms acidic oxide like Cl₂O₇ , Cl₂O₃ etc

These oxides are covalent compounds .

So V may have 6 or 7 electrons in the outermost orbit .

Hence option D is the right answer.
