Alcohol SolubilityWhat is the structure for hexadecanol?
What would explain why it is a solid, rather than a liquid?
How are ethanol, 1-octanol, propane-1,2,3-triol, and hexadecanol similar to their corresponding hydrocarbons (ethane, octane, propane, & hexadecane)?
Do some of these alcohols possess more hydrocarbon character than others? Which ones? Why is that?
How are they different from their corresponding hydrocarbons?
Are they all soluble in water?
What about solubility in hexane?
The heat of solution of ammonium nitrate is 26.2 kJ/mol. If a 5.368 g sample of NH4NO3 is added to 40.0 mL of water in a calorimeter at 23.5°C, what is the minimum temperature reached by the solution.
