Rank the following in terms of decreasing miscibility in C₈H₁₈ (octane), a major component of gasoline:
Aleksandr-060686 [28]

Answer:

In order of decreasing miscibility

C₉H₂₀ (nonane)→C₂H₅F (fluoroethane)→C₂H₅Cl (chloroethane)→H₂O (water)

Explanation:

The solubility of a solid is a measure of its ability to dissolve in a liquid while for liquids,  the miscibility is a measure of thhe liquid to mix with anoyjer liquid resulting in a soltion which can hold any amount of either liquids. Immiscible liquids are those that are not soluble or have very limited solibility with each other.

C₉H₂₀ (nonane)→C₂H₅F (fluoroethane)→C₂H₅Cl (chloroethane)→H₂O (water)

In the order of decreasing miscibility as like dissolve like, ability to dissociate and polar and organic characteristics are considered

An element A combines with element B. The electrons are transferred from the atom A to the atom B. .
Sloan [31]

(a) The nature of bond between A and B is an ionic bond.

(b) The two main properties of the ionic compounds are:

  • Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break.
  • The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions.

(c) If the ionic compound is dissolved in water, the ions in the solid separate and disperse uniformly

<h3>What is an ionic compound?</h3>

Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions.

An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion.

In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution.

If uranium-235 is bombarded with a neutron, it will temporarily become
stealth61 [152]
All atoms consist of a nucleus with protons and neutrons that is surrounded by a sea of electrons. If Uranium-235 is bombarded with a neutron then the atom's atomic number will remain the same but its mass will increase by 1 unit. Thus, it will temporarily become Uranium-236.

What is the molarity if I take 10mL of 20 volumes Hydrogen Peroxide?
Kryger [21]

Answer:

1.635 M

Explanation:

Given:

10 mL of 20 volumes Hydrogen Peroxide

Here,

20 volumes of Hydrogen Peroxide means that on decomposition of 1 mL of H₂O₂ 20 mL of O₂ is obtained

also,

means 1 dm³ of H₂O₂ solution produces 20 dm³ oxygen

Now,

at 298K and 1 atm

20 dm³ oxygen = \frac{\textup{20}}{\textup{24.47}}  moles

or

= 0.817 moles

also,

2H₂O₂ → 2H₂O + O₂

thus,

1 dm³ of solution must contain 2 × moles of O₂ as moles of H₂O₂

thus,

Number of moles of H₂O₂ = 2 × 0.817

or

Number of moles of H₂O₂  = 1.635 moles

Hence,

For 20 volume hydrogen peroxide is 1.635 M
