Write any 2 uses of fractionate distillation​

Chemistry
1 answer:
balandron [24]3 years ago
3 0

Answer:

Fractional Distillation could be used to:

  1. Obtain the different fractions of a crude which may have more uses and be more useful.
  2. Obtain ethanol from a mixture of ethanol and water.

Fractional Distillation is used to obtain one substance from a mixture. It depends on the boiling points of the substances.

In terms of intermolecular forces why ethanol has a much higher boiling point than ethene at standard point
leva [86]
Ethanol contains an alcohol group (-OH), which includes hydrogen bonding. Hydrogen bonding is stronger than other IMFs such as Van der Waals forces and Dipole-Dipole.

Ethene only has Van der Waals forces as it is an alkene with only C-H or C-C bonds. These means that the forces are not as strong.

Since ethanol contains hydrogen bonding, it will take a higher temperature in order to break these bonds, and thus results in a higher boiling point than ethene.

The specific heat capacity of aluminum is 0.22 cal/g°C. How much energy needs to flow into 20.0 grams of aluminum to change its
True [87]

Answer:

C)  66 calories

Explanation:

The Heat energy required to flow into a unit mass object to raise its temperature by 1 degree is known as specific heat capacity.

specific heat capacity of aluminum, c = 0.22 cal/g°C

mass of aluminium, m = 20.0 g

Why is CCl4 a nonpolar molecule, but PCl3 is a polar molecule?
Anna11 [10]
If you follow the octet rule, you know that an element must have 8 outside (or valence) electrons to be energetically favorable.

In CCl4, the carbon molecule forms four bonds; one for each chlorine atom. Each bond contains 2 electrons, so it is satisfied.

In PCl3, Phosphorous forms only 3 bonds with chlorine, which means in order to have 8 valence electrons, it also has a lone pair of electrons, not bonded with chlorine.

Now, in CCl4, picture the shape of the molecule like a plus sign, with the carbon in the middle and the chlorine at the four ends. It is symmetrical, and therefore is nonpolar.

In PCl3, the lone pair electrons <em>push</em>, so to speak, the 3 chlorine atoms away, making a T-shaped molecule.  Since the chlorine is more electronegative than carbon, the molecule is unbalenced, making it polar.
