Which sentence correctly explains the process and conditions needed for sleet to form?
laiz [17]

Answer:Sleet only happens under very specific weather conditions. There must be a layer of air near the ground whose temperature is below freezing, where water turns to ice. Above this layer of freezing air must be a layer of warmer air. As snow falls through the warm air, it melts or partially melts into raindrops.

What attractive forces must be overcome when CsI is dissolvedin<br> liquid HF?
bagirrra123 [75]

Answer:

The attractive forces must be overcome are :

  • Ion- ion interaction
  • Dipole - Dipole  
  • Hydrogen Bonding  

Explanation:

For the compound to dissolve the attractive forces existing between atoms of the compound must be reduced

<u>CsI is ionic compound </u><em>and its molecules are held together by ionic(electrostatic) force . These force must be weakened for its dissolution</em>

Forces in HF <em>:</em>

<em>1 .Hydrogen Bonding :  In HF strong intermolecular Hydrogen Bonding exist between the electronegative F and Hydrogen</em>

2. Dipole - dipole : <em>HF is polar . So it is a permanent dipole and has dipole diople interaction</em>

2 CuCl2 + 4 KI → 2 CuI + 4 KCl + I2
Margaret [11]

Answer: 6.75 moles

Explanation:

This is a simple stoichiometry proboe. that I would set up like this:

(13.5 moles CuCI2) (1 mol I2 / 2 moles CuCi2)

That means you all you have to do for this problem is divide by 2 and cancel out the unit moles CuCI2, which leaves you with 6.75 moles I2.

Hope this helps :)
