Answer:
<u>Homogeneous mixture:</u>
- These are called solutions.
- It has a uniform composition.
- It has only one phase.
- It cannot be separated physically.
- The particles appear smaller in size.
- These are pure substances.
- These are not visible easily visible to the naked eye and also through a microscope.
- Examples include milk, gasoline, sugar solution, corn oil, fog, etc.
<u>Heterogeneous mixture:</u>
- These are called suspensions/colloids.
- It has a non-uniform composition.
- There are two or more phases.
- It can be separated physically.
- The particles are either smaller or larger in size.
- These are not pure substances.
- These are easily visible to the naked eye and also through a microscope
- Examples are- a mixture of mud & water, beach sand, vinegar, air cloud, etc.

Answer:
In the formation of diazonium ion intermediate, the <em><u>4-sulfanilic acid acts as the Lewis acid</u></em>, while the <em><u>sodium nitrite is the Lewis base.</u></em>
Explanation:
A Lewis acid is by definition an electron pair acceptor (such as the H+ ion, that can accept a pair of non-bonding electrons) and a Lewis base is an electron pair donor (such as the OH- ion, that can donate a pair of non-bonding electrons).
In the formation of diazonium ion intermediate, the 4-sulfanilic acid acts as the Lewis acid(by transference of a lone pair from its nitrogen atom), while the sodium nitrite is the Lewis base.
<em>N.B </em><em>its sodium nitrite, NaNO2 (which is slightly basic in solution) not nitrate NaNO3 (which is neutral in solution)</em>
Answer:
Explanation:
Hello there!
In this case, considering that the heat has two forms, sensible (variable temperature) and latent (constant temperature), we can notice that phase changes account for latent heat as the temperature remains the same. In such a way, given the enthalpy of vaporization of water, 40.67 kJ/mol, the enthalpy of condensation (reverse process) is the negative value, -40.67 kJ/mol; therefore, the associated latent heat would be:
