CO2, C2H2, BeF2, XeF2, etc all these molecules have linear geometry.

Explanation:

There are a few examples of different type of molecules that have a linear geometry:

1) Diatomic molecules

Diatomic molecules always have a linear geomerty given that its their only possiblility.

Some examples are: Oxygen (O2), Nitrogen (N2), Fluorine (F2), Choridic acid (HCl).

2) Triatomic molecules with no lone pair electrons

In this case, the absence of lone pair electrons keeps a linear geometry in molecules such a carbon dioxide (CO2).

If the molecule would have this electrons the repulsion generated between them and the electrons from the atomic bonds would create an angular geometry.

Why must the spot applied to a TLC plate be above the level of the developing solvent? What problem will ensue if the level of t

algol13

Answer:

See explanation

Explanation:

If the spot in TLC is below the solvent front, it will be observed that the spot, instead of being separated by the solvent as expected, will just dissolve away in the solvent and zero actual separation of the mixture is achieved.

If the solute is dissolved away instead of being separated by the solvent, then the experiment fails because no actual separation of the mixture is achieved.

Hence, in TLC, the spot must be applied above the solvent front so that the capillary movement of the solvent through the plate can lead to the eventual separation of the components of the mixture since the various components of the mixture will travel at different speeds through the plate.

Also, if the solvent is above the spot, the solvent may evaporate selectively from the points above the spot while separation is ongoing.

Sergio039 [100]

Answer:

The false statement is: 3. Because liquid water and liquid carbon tetrachloride do not mix, neither do their vapors

Explanation:

Gas is a state of matter, that has less density than liquids and solids. The gaseous particles have low intermolecular forces and thus they can move freely.

It is a very compressible fluid that has no fixed shape. Gas occupies the whole container in which it is stored, thus taking the shape of the container. Therefore, the volume of the gas is equal to the volume of the container.

Polar liquid like water (H₂O) and nonpolar liquid like carbon tetrachloride, are immiscible. However, in the gaseous state, their vapors form a homogeneous mixture.
