Answer is: 1. decane, c10h22

This pair will most likely form a homogeneous solution because they are both nonpolar substances and "like dissolves like".

Other pairs will not form homogeneous solution because polar (methanol, sugar) or ionic (h<span>ydrofluoric acid)</span> substances have low solubility in nopolar (benzene) substances.

Decane can be the most miscible species in benzene.

Answer: 1. decane, c10h22

Explanation

The miscibility is the measure of solubility of a solute in a solvent.

As per the rules of solubility, like substances dissolve and unlike substances get suspended.

So here benzene is a non-polar solvent, so the solute which can be most miscible in benzene should also a non-polar nature.

Thus the solute should be non-polar substance to dissolve in non-polar solvent.

Among the options given, decane C10H22 is the non-polar substance which can act as solute.

Thus decane can be the most miscible species in benzene.

Select all that are true regarding stereoisomers,constitutional isomers, and conformational isomers
Tamiku [17]

Answer:To convert the model of one constitutional isomer to another constitutional isomer one needs to exchange 2 atoms/groups on different atoms.

To convert the model of one stereoisomer to another stereoisomer one needs to exchange 2 atoms/groups bonded to the same carbon.

To convert the model of one conformational isomer to another conformational isomer one only needs to rotate about single bond(s).

Explanation:

Constitutional isomers differ from each other in position of substituents. Hence if we interchange atoms or groups on two different atoms, we get constitutional isomers.

Stereo isomers posses different orientations in space. If two atoms or groups on the same carbon atoms interchange their spatial orientation, we have a different stereoisomer other than the original structure.

Conformers arise by free rotation across single bonds. Different conformers can be created by rotating single bonds.

Which pair of elements is most apt to form an ionic compound with each other?
sweet [91]
Ionic compounds are compounds that are formed together by a cation and an anion. A cation is an ion with a positive charge. For example, Na+ and Ca2+. An ion has a negative charge, like Cl- and OH-. There is a greater chance of forming an ionic compound when they have a great difference in electronegativity, the ability to attract electrons toward itself. In the periodic table, elements that are opposite to each other, more likely found in opposite sides, would be more apt to form an ionic compound. Example would be NaCl and CaCl2 or Ca(OH)2.

For the reaction H2PO4- HAsO4 2-HPO4 2-+H2AsO4- <br> what species are a conjugate acid-base pair?
aleksklad [387]

Ionic equation:

\text{H}_2\text{PO}_4^{-} + \text{HAsO}_4^{2-} \to \text{HPO}_4^{2-} + \text{H}_2\text{AsO}_4^{-}

The acid and base in a conjugate pair differ by only one proton \text{H}^{+}. The acid loses one proton to produce a conjugate base, whereas the base gains a proton to produce its conjugate acid.

\text{H}_2\text{PO}_4^{-} loses one proton to produce \text{HPO}_4^{2-} in this reaction.

\text{H}_2\text{PO}_4^{-} \to \text{H}^{+} + \text{HPO}_4^{2-}

Meanwhile, \text{HAsO}_4^{2-} gains one proton to form \text{H}_2\text{AsO}_4^{-}.

\text{HAsO}_4^{2-} + \text{H}^{+} \to \text{H}_2\text{AsO}_4^{-}

Therefore

  • \text{H}_2\text{PO}_4^{-} is the conjugate acid  \text{HPO}_4^{2-}, its conjugate base.
  • \text{HAsO}_4^{2-} is the conjugate base of \text{H}_2\text{AsO}_4^{-}, its conjugate acid.

HELP I WILL MARK YOU AS THE BRAINLIEST ANSWER
borishaifa [10]

Hey there! Here is the answer:

B.) decrease; increase

Here's why:

As you move from left to right across a period on the periodic table the size of an atom will decrease. As you move from top to bottom down a group on the periodic table the size of an atom will increase.

I really hope this answer helps you out! :)
