In the presence of an emulsifying agent, a mixture of oil and water becomes a _____.
Alex Ar [27]

Answer:

Colloidal dispersion or emulsion

Explanation:

The colloid of a liquid in liquid (both dispersed phase and dispersion medium are liquids) is known as emulsion or colloidal dispersion.

We know that oil and water are immiscible liquids. In order to make them miscible we have have add emulsifying agents.

An emulsifying agent has a long non polar hydrocarbon chain (in general) and a polar head.

For example salts of fatty acids.

The polar head is hydrophilic and non polar tail is hydrophobic.

It causes the miscibility of the two polar and non polar liquids

Why do chemically active metals have low electronegativity values?
sdas [7]
Active metals are those metals in the group 1 of the periodic table.

Electronegativity is the trend to atract electrons.

Active metals have few valence electron, because their last shell is of the kind ns^1 or ns^2

Then, these atoms do not trend to attract electrons. The most electronegative atomos are those who have 7 valence elecfrons; this is their last shell is of the kind ns^7, because when they attract one electron to its valence shell they will complete 8 electrons which is the most stable configuration.

1.Why mixture of stone pebbles and water is considered a suspension? Write few properties of the suspension. How suspension diff
sergey [27]

Explanation:

1.A mixture of stone, pebbles, and water is an example of a suspension. Because the particle size is more than 1000nm.

Properties of suspensions:

Suspension is a heterogeneous mixture. The constituents of the mixture are clearly visible.

The particle size will be more than 1000nm. If the suspension is left undisturbed then the particles will settle down.

Properties of Colloids:

Whereas in colloidal solutions, the particle size is in between 1nm-1000nm.

The particles will never settle down in colloid.

They show the Tyndall effect.

2.The solubility of salt at 20^oC is 30. That means the maximum amount of salt that is present in 100 g of water is 30 g.

If the temperature of a saturated solution is increased then, its solubility increases or decreases based on the nature of the solute.

For example if we take sodium chloride salt ,then its solubility is not effected by the change in temperature.

For cerium sulphate salt if temperature increases, then its solubility in water  decreases.

For sugar (sucrose) its solubility increases with increase in temperature.
