Consider the molecules HCl, HBr, HF, and HI. Which would you expect to have the highest boiling point and why

Chemistry
1 answer:
FrozenT [24]3 years ago

Answer:

C) HF, because it has the strongest intermolecular force  

Explanation:

The electronegativity difference ΔEN between H and F is so high that HF has especially high dipole-dipole forces, which we call hydrogen bonds. They are the strongest intermolecular forces, and they are responsible for the high boiling point of HF.

A) is wrong. HI has a higher mass and more electrons than HBr.

B) is wrong. There is no hydrogen bonding in HCl.

D) is wrong. There are no ion-dipole forces in HI.

What would be the voltage (Ecell) of a voltaic cell comprised of Cd(s)/Cd2+(aq) and Zr(s)/Zr4+(aq) if the concentrations of the
lutik1710 [3]

Answer:

1.05 V

Explanation:

Since;

E°cell= E°cathode- E°anode

E°cathode= -0.40 V

E°anode= -1.45 V

E°cell= -0.40-(-1.45) = 1.05 V

Equation of the process;

2Zr(s) + 4Cd^2+(aq) ---->2Zr^4+(aq) + 4Cd(s)

n= 8 electrons transferred

From Nernst's equation;

Ecell = E°cell - 0.0592/n log Q

Ecell= E°cell - 0.0592/8 log [0.5]/[0.5]

Since log 1=0

Ecell= E°cell= 1.05 V
