what is the boiling point of a solution containing 2.33 grams of C8H10N4O2 , dissolved in 15 grams of benzene? The boiling point of pure benzene is 80.1 C . and the boiling point elevation constant ,Kbp, is 2.53C/m
The vapor pressure of a liquid is the pressure exerted by its vapor when the liquid and vapor states are in equilibrium. The relationship between vapor pressure and temperature is expressed by the Clausius-Clapeyron equation.
determine the initial concentration - Constant rate is 3.20×10-4 M/s for a zero-order reaction. concentration has dropped to 9.00×10-2 M after 60.0 seconds
what would you expect to observe if KHCO3 reacted with H2SO4? what test would you perform to identify the product?
Give equations for the reaction of salicylic acid with the following: a) acetyl chloride/pyridine b) methanol/HCl/heat c) sodium bicarbonate, room temperature
