What is the difference between a suspension, colloid, and a solution? (IF ANSWER IS GOOD AND CORRECT I WILL GIVE BRAINLIEST)

Chemistry

Firlakuza [10]3 years ago
7 0

A solution is always transparent, light passes through with no scattering from solute particles which are molecules in size. The solution is homogeneous and does not settle out. A solution cannot be filtered but can be separated using the process of distillation.

A suspension is cloudy and heterogeneous. The particles are larger than 10,000 Angstroms which allows them to be filtered. If a suspension is allowed to stand the particles will separate out.

A colloid is intermediate between a solution and a suspension. While a suspension will separate out a colloid

will not. Colloids can be distinguished from solutions using the Tyndall effect. Light passing through a colloidal dispersion, such as smoky or foggy air, will be reflected by the larger particles and the light beam will be visible.

A pure substance is a solid, liquid or gas which molecules which are all identical, or an infinite crystaline polymer in which all unit cells are the same.

ICl has a higher boiling point than Br2. What is the best explanation for this?
Burka [1]

Answer:

b. ICl experiences dipole-dipole interactions

Explanation:

The molecule with the <em>stronger intermolecular forces</em> will have the higher boiling point.

In Br₂, the Br-Br bond has a <em>dipole moment of zero</em>, because the two atoms are identical.

In ICl, the I-Cl bond, has two different atoms. One must be more electronegative than the other, so there will be a <em>non-zero bond dipole</em>.

ICl will have the higher boiling point.

a is <em>wrong</em>. Br₂ is nonpolar, so it has no dipole-dipole interactions.

c is <em>wrong</em>. Br₂ cannot form hydrogen bonds, because there is no hydrogen.

d is <em>wrong</em>. ICl has dipole-dipole interactions.

A galvanic cell at a temperature of 42°C is powered by the following redox reaction:
WARRIOR [948]

Answer:

1.99V

Explanation:

Balanced redox reaction equation:

3CU2+(aq) + 2Al(s) ------> 3Cu(s) + 2Al3+(aq)

E°cell= E°cathode- E°anode

E°cell= 0.34-(-1.66)

E°cell= 2.0V

From Nernst equation:

E= E°cell - 0.0592/n logQ

E= 2.0 - 0.0592/6 log [3.43]/[1.63]

E= 2.0- 0.0032

E= 1.99V
