Place these hydrocarbons in order of decreasing boiling point.
Rank from highest to the lowest boiling point. To rank items as
equivalent, overlap them.
Paraffin, butane, octane, (2,2,4 trimethylpentane),
octadecane
Rank these aqueous solutions from highest boiling point to
lowest boiling point.
1 = highest boiling point; 4 = lowest boiling point
0.40 m C2H6O2
0.20 m Na3PO4
0.30 m KNO3
0.20 m C6H12O6
10. Arrange the following compounds in a vertical list from
highest boiling point (top) to lowest boiling point (bottom) and
explain your answer on the basis of whether the substance is Polar,
Nonpolar, Ionic, Metallic or Hydrogen bonding: O2, KF, NH3, Cu, HBr
(Please note in this question you are not being asked to list BPs
but the compounds in a list from highest to lowest BP on the basis
of the type of compound.)
Rank the sets of compounds from
lowest to highest boiling point. justify your answer
- propanol and isopropanol, - butanol, isobutanol, and t-butyl
alcohol,- ethanol, ethylene glycol and glycerine
1. List the following aqueous solutions in order of increasing
boiling point: 0.120 m glucose, 0.050m LiBr,0.050m Zn(NO3)2
2. we are told that the vapor pressure of ethanol (CH3CH2OH) at
20C is 45 torr. The vapor pressure of methanol (CH3OH) at 20C is 92
torr. Calculate thevapor pressure of a solution which contains 25 g
of methanol and 75 g of ethanol.
1. List the following substances in the order from lowest to
highest surface tension:
water (H2O)
acetone (CH3COCH3)
ethyl alcohol (C2H6O)
2. Why did you put them in this order?
3. What is the definition of viscosity?
How would a decrease in temperature change the viscosity of a
substance?
How would a increase in temperature change the viscosity of a
substance?
List the following substances from least viscosity to most
viscosity: honey, motor oil, water
