Methanol (CH3OH), which is used as a cooking fuel, undergoes combustion to produce carbon dioxide and water. Write the equation for the chemical reaction?
The solubility of benzoic acid in water is 5.9 g/100 mL at 100°C; 0.30 g/ 100 mL at 25°C; and 0.17 g/100 mL at 0°C. Can a mixture of approximately equal amounts of benzoic acid and salicylic acid be separated by recrystallization? Explain.
