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>

A chemist heats 100.0 g of FeSO4 x 7H2O in a crucible to drive off the water. If all the water is driven off, what is the mass o
Ierofanga [76]
FeSO₄*7H₂O(s) = FeSO₄(s) + 7H₂O(g)

M(FeSO₄*7H₂O)=278.0 g/mol
M(FeSO₄)=151.9 g/mol

m(FeSO₄*7H₂O)/M(FeSO₄*7H₂O)=m(FeSO₄)/M(FeSO₄)

m(FeSO₄)=M(FeSO₄)m(FeSO₄*7H₂O)/M(FeSO₄*7H₂O)

m(FeSO₄)=151.9*100.0/278.0=54.6 g

m(FeSO₄)=54.6 g
