ow do the properties of a nonhomogeneous (heterogeneous) mixture differ from those of a solution? Give two examples of nonhomogeneous mixtures.
Caffeine is made up of 49.5% C, 5.2% H, 16.5% O, and 28.9% N. A solution made up of 8.25 g of caffeine and 100.0 mL of benzene (d=0.877g/mL) freezes at 3.03C. Pure benzene (k f =5.10C/m) freezes at 5.500C. What are the simplest and molecular formulas for caffeine?
An investigation was carried out to determine which of three antibacterial soaps is most effective. Four petri dishes labeled A, B, C, and D were set up. The same amount and type of bacteria was added to each dish. Next, 2 mL of a different brand of soap were added to dishes B, C, and D. Then, 2mL of water was added to dish A, instead of soap. The dishes were incubated at 37o C for 24 hours. At the end of the investigation, the amount of bacteria in each dish was determined. Dish D had the least bacteria. It was concluded that the soap in dish D was the most effective soap to use against bacteria. Which statement best describes the validity of this conclusion?

The picture is 1.)A 1B.) If DHsolution for dissolving DMSO in methanol is negative, what does this say about the energy released in mixing methanol and DMSO molecules (DHmixing) as compared to the energy required in separating solute molecules from each other (DHsolute) and separating solvent molecules from each other (DHsolvent)? What can you conclude from this about the strength of DMSO-methanol interactions? Which “wins” in this case? Enthalpy? Entropy? Both? Explain
