In an experiment, two unknown compounds (one an ether and the other an amine) of equal molecular mass were dissolved in water. The result of the experiment is shown in the table. Solubility Comparison
Unknown Compound Solubility (g/100 ml water)
A 4
B 0.25

Which of the following correctly explains the identity of Compound A and its solubility?
It is an amine; it contains a nitrogen atom that will allow nitrogen-hydrogen bonds to form while in water.
It is an ether; because the oxygen atom is within the carbon chain, so it is free to form oxy-hydrogen bonds to make it more soluble.
It is an ether; the high polarity of the oxygen-hydrogen bond makes it more soluble.
It is an amine; because the lower electronegativity of N than H makes it more soluble.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
