The barometric pressure of a room at 26 degrees C is found to be 752.0 mm Hg. The vapor pressure of water at this temperature is 25.2 mm Hg. What is the partial pressure of H2 in a buret in this room during a similar experiment to this one?   options:   777.2 mm Hg   752.0 mm Hg   726.8 mm Hg   25.2 mm Hg

1. Discuss the three main intermolecular forces described in chapter 11 using relevant examples. 2. List the following substances: Ar, Cl2, CH4 and CH3COOH in order of their increasing strength of intermolecular attractions. Give reason for your answer. 3a. Which intermolecular force is present in Water? Explain the reason for your answer. b. Some of the remarkable consequences  of the intermolecular force present in water can be used to explain the  "Expansion of water upon freezing", which explains why icebergs float in water and why water pipes burst in freezing temperatures.   Question: Using the concept of the intermolecular force present in water: Discuss why water expands upon freezing.  4."CH3OH boils at 65*C, while CH3SH boils at 6*C" . Which intermolecular force accounts for this difference? Explain. Respond to one student's post.

Select the appropriate options to identify which compound in the following pair has the lower freezing point and identify the strongest intermolecular forces for that compound: CH3CH₂CH₂OH (n-propanol) or CH3CH₂CH3 (propane) has the lower freezing point. The strongest intermolecular forces of the compound with the lower freezing point are 1. CH3CH₂CH₂OH (n-propanol) 2. CH3CH₂CH3 (propane) 3. ion-dipole forces 4. hydrogen-bonding forces 5. dipole-dipole forces 6. ion-induced dipole forces 7. dipole-induced dipole forces 8. dispersion forces
