Which of the following is/are example(s) of a heterogeneous mixture? a) Colloidal solution b) Suspension c) Solution
(a) and (b)
A colloidal solution and a suspension both have visibly distinct, non-uniformly distributed particles and are therefore heterogeneous mixtures, while a true solution is homogeneous.
Hence, the correct answer is (a) and (b).

A non-volatile solute, urea ($CO(NH_2)_2$, molar mass $60 \ g/mol$), is dissolved in $180 \ g$ of water ($H_2O$, molar mass $18 \ g/mol$). If the vapor pressure of pure water at a certain temperature is $50 \ mmHg$, what is the vapor pressure of the solution when $18 \ g$ of urea is added?
