This graph shows how the vapor pressure of three liquids varies with temperature: vapor pressure, torr 900 800 700 600 500 400 300 200. 100 0 50 60 70 80 temperature, °C Use the graph to answer the following questions: Which liquid is the most volatile? Which is the least volatile? What is the normal boiling point of each liquid? Note: your answer must be within 1°C of the exact answer to be graded correct. Suppose a beaker of isopropyl acetate is put inside a sealed tank containing isopropyl acetate gas at 80. degree C and 858. torr. After ten minutes, will there be more liquid in the beaker, less liquid, or the same amount? - chloroform isopropyl acetate benzene most volatile: 90 least volatile: chloroform: isopropyl acetate: benzene: more less the same choose one choose one °C °C °℃

3. Using your knowledge of IMF's, rank the following in order of increasing expected vapor pressure. Make sure to explain your logic and indicate which intermolecular force(s) each is capable of forming. H H H H H H H H H ✓ с H H H C H H C. H

If the solid form of a pure substance is denser than its liquid form, an increase in pressure will cause the melting point to decrease. True or False True False

PLease be detailed in your explination. Write a whole paragraph on it. Also explain using a diagram as well

Ice floats because of the electronegativity of oxygen that withdraws electron density from the covalently bonded hydrogens. This results in a permanent dipole, leaving a partial positive charge on the hydrogens. The extra electron density on the oxygen leaves a partial negative charge. Therefore, water is a polar molecule and has the ability to form hydrogen bonds. These properties explain many of water's characteristics, including why ice is less dense than liquid water.
