Predict differences in our global environment that may havearisen if the freezing point and boiling point of water were208C higher than they are

Calculate the freezing point and boiling point of a 0.55 m  CH3OH in water. (Kf = 1.8oCkg/mol;  kb= 0.51 oC kg/mol).

In what context do the terms hydrophobic and hydrophilic relate to the solubilities of substances in water?

At room temperature, toluene has a vapor pressure of 300mmHg and ethanol has a vapor pressure of 45mmHg. Let us assume that when equimolar amounts of these liquids are mixed together, heat is released. What can be said about the vapor pressure of the resulting solution? O The vapor pressure will be 172.5 mmHg because there are equal amounts of both liquids. O The vapor pressure is less than 172.5 mmHg because the reaction is exothermic. O The vapor pressure will be 300 mmHg because toluene has the greater vapor pressure, which cancels out the vapor pressure of ethanol. O The vapor pressure will be 345 mmHg because the vapor pressure values are additive.
