Question

Hello I need some helpI need to find the correct sketch in each set with the follow:Melting point of HCI: -114.8 cBoiling point of HCI: -85.1 coption A says -97c,B says -37c, C says 124 c

Answer 1

We have the melting and boiling point of HCl.

The melting point is the temperature at which HCl will change from solid to liquid. Below this temperature, HCl will be solid and the molecules will be very organized and close.

Up to this temperature, HCl will be liquid. The molecules will be a little more disorderly than in the solid state.

The boiling point is the temperature at which HCl will change from liquid to a gaseous state. Below this temperature HCl will be liquid, up to this temperature HCl will be gaseous and the molecules will be very far from each other.

Now, with the given data we have that the states of HCl depending of the temperature will be:

Gaseous state: Temperature> -85.1 C

Liquid state: -114.8 C < Temperature < -85.1 C

Solid state: Temperature < -114.8 C

Now, we have three options given, the state for each option will be:

A. -96 C, HCl will be in Liquid

B. -37 C, HCl will be gaseous (Molecules higly disorganized and far from each other)

C. -124 C, HCl will be solid (Very organized)

Therefore the correct option will be:
