Phosphorus trichloride, PCl₃ is a liquid at room temperature.

Chemistry
1 answer:
Simora [160]3 years ago
4 0

Answer:

Phosphorus trichloride, PCl₃ undergoes change in bonding and molecular force of attraction, causing it to be liquid at room temperature.

Explanation:

Unlike other chlorides of Period 3 elements, Phosphorus trichloride, PCl₃ changes the structure of its molecular bonding from ionic to covalent bonds as it transitions to fluids (liquids or gases). The PCl₃ molecule also has the weak Van der Waals dispersion and dipole-dipole attraction, making it a fuming liquid at room temperature,  with no electrical conductivity.

1. Stirring increases the rate of solution
Blababa [14]

Answer:

1) <em>The correct answer is A. Collision</em>

2) A hot solvent helps a solid dissolve faster because an increase in <u><em>kinetic energy</em></u> that also increases the rate of collisions

Explanation:

When a solute is added into a solvent and stirred, the solute particles get distributed to all parts of the solvent as a result of stirring.

More collisions occur between the solute and the solvent due to stirring. This increases the rate of dissolving.

<em>When a solvent is heated, then the kinetic energy would increase and the atoms will collide with a much greater force. As a result, ore solute will be able to dissolve in the solvent. </em>

Write a 4-line paragraph to explain what is melting.
natali 33 [55]

Answer:

Melting  is the process of being changed from a solid to a liquid state especially by the application of heat. This occurs when the energy of the solid increases, which increases the substance's temperature to the melting point.  Typically, the solids energy increases by the application of heat or pressure. At the melting point, the ordering of molecules in the solid breaks down to a less ordered state, and the solid "melts" to become a liquid.

hope this helps! :)

I need help, I don't understand the question
Oduvanchick [21]
Remember this. 

Ionic molecules has ionic bonds
Nonpolar molecules has dispersion (Van del Waals)
Polar molecules could either have hydrogen bonding or Dipole-Dipole. Hydrogen bonding is when you have F, O or N with H, every other polar molecule is dipole-dipole.

a. polar- dipole-dipole
b. polar- hydrogen bonding
c. nonpolar- dispersion
d. nonpolar- dispersion
e. polar- dipole-dipole
f. polar-dipole-dipole
g. nonpolar- dispersion
h. polar- hydrogen bonding.

Now that we have put a coefficient of 3 in front of caso4, what coefficient should go in front of cacl2 to balance calcium (ca)?
Ronch [10]
3 to balance the calciums on both sides of the equation, but only if that balances the Cl on both sides of the equation to because you now have 6 Cl and 3Ca
