Question

Consider the following colligative properties of an aqueous glycol (nonvolatile molecule) solution. Is each property lower than, equal to, or higher than that of water? Vapor pressure: ____ Freezing point: _____ Boiling point: _____ What are three factors which control reaction rate? Would you increase or decrease each of the three factors to speed up a chemical reaction rate? a) Factor 1: _____ b) Factor 2: _____ c) Factor 3: _____ For the equilibrium, N_2O_4(g, colorless) rightarrow 2NO_2(g, orange) delta H > 0, give three methods to turn the mixture less orange. a) Method 1: _____ b) Method 2: _____ c) Method 3: _____ Calculate [OH^-], and pH for 1.0 times 10^-3 M aqueous KOH solution. Calculate the molar solubility of Mn(OH)_2 (K_sp = 1.6 times 10^-13) in 0.010 M NaOH. Name the complex, Pb(NH_3)_2 Cl_2, and sketch two geometric isomers, labeling cis/trans.
