What kind of intermolecular forces act between a hydrogen cyanide (HCN) molecule and a hydrogen bromide molecule?
Note: If there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force.
State the kind of intermolecular forces that would occur between
the solute and solvent in acetic acid (polar, contains an OH group)
solution
Check all that apply.
dispersion
hydrogen bonding
ion-dipole
dipole-dipole

to interact with neighboring
molecules of the same kind?
A. London dispersion forces only
B. Dipole/dipole forces only

D. London dispersion forces and dipole/dipole forces
E. All three intermolecular forces
Potassium cyanide (KCN) reacts with acids to form a deadly
poisonous gas, hydrogen cyanide (HCN). The reaction is represented
by the equation:
KCN(aq) + HCl(aq) è KCl(aq) + HCN(g)
If a sample of 0.150 g of KCN is treated with an excess of HCL,
calculate the amount of HCN produced, in grams.
Hydrogen cyanide, HCN, is a poisonous gas. The lethal dose is
approximately 300. mg HCN per kilogram of air when inhaled. The
density of air at 26 ∘C is 0.00118 g/cm3. Consider the formation of
HCN by the reaction of NaCN (sodium cyanide) with an acid such as
H2SO4 (sulfuric acid):
2NaCN(s)+H2SO4(aq)→Na2SO4(aq)+2HCN(g)
What mass of NaCN gives the lethal dose in the room? partc:
HCN forms when synthetic fibers containing Orlon® or
Acrilan® burn. Acrilan® has an empirical
formula of...

part a.
Calculate the amount of HCN that gives the lethal dose in a
small laboratory room measuring 12.0 ft×15.0 ft×8.60ft .
Express your answer to three significant figures and include the
appropriate units.
