What is the boiling point of the automobile radiator fluid prepared by mixing 1.02 L of ethylene glycol (HOCH2CH2OH, density = 1.114 g/mL) with 1.04 L of water (density = 1.000 g/mL)?
TRUE OR FALSE: 1. Solids such as naphthalene when heated will pass thru a process called condensation prior to sublimation when being purified. 2.If water and n-propyl alcohol were mixed, the separation of individual components is possible with steam distillation because these two have a wide range of boiling point difference. 3. When an impurity in the synthesized camphor such as sodium chloride is present, the sublimation technique cannot be used to purify the camphor due to the nature of NaCl. 4. Organic solvents such as hexane or ether are an excellent medium to recrystallize an impure benzoic acid 5.
