Which of the following will be most soluble in octane?

Chemistry
1 answer:
natima [27]3 years ago
7 0

Answer:

CH3CH3CH2CH3

Explanation:

Octane is a non-polar compound. It is a hydrocarbon with 8-carbon length along its chain.

It belongs to a special group of hydrocarbons called alkanes.

What makes a substance soluble in another?

   It is a common phrase that  "like dissolves like". This is applicable to solubility of substances in another.

  • A polar solvent will freely and easily dissolve a polar solute. For example, water and salt.
  • A non-polar solvent will also dissolve a non-polar solute. This case, hydrocarbons will dissolve themselves.
  • The first option is a butane, a 4-carbon length hydrocarbon which will be dissolved in octane.
  • Both compounds are non-polar.

What is the net ionic equation for 2Sb(OH)3 (s) + 3Na2S (aq) = Sb2S3 + 6NaOH
tatuchka [14]

Answer:

2Sb^(+3) (aq) + 3S^(-2) (aq) = Sb_2•S_3

Explanation:

First of all, let us balance the equation to give;

2Sb(OH)3 (s) + 3Na2S (aq) = Sb2S3 + 3NaOH

Now, we can observe the presence of positive Sodium ions (Na+) and negative hydroxyl ions (OH-) on both left and right sides of the equation.

Now, the two ions will cancel out. These ions are not really involved in the overall reaction and thus do not require being written in the overall equation. Hence, the overall net ionic reaction can now be written as:

2Sb^(+3) (aq) + 3S^(-2) (aq) = Sb_2•S_3
