Calculate boiling point of a solution of 500.0 g of ethylene glycol dissolved in 500.0 g of water. kf = 1.86 c/m and kb = 0.512 c/m. Use 100 degrees celsius as the boiling point of water.
Which of the following can be the product of a neutralization reaction?
How much heat is required to warm 1.20 L of water from 20.0 degrees C to 100.0 degrees C ? (Assume a density of for the water.)
A 250 g sample of sucrose C12H22O11(s) was burned in a 21.00 kg iron calorimeter immersed in 1.450 Kg of water. The initial temperature of the system was 24.32 degrees Celsius. Determine the heat of combustion of sucrose under the conditions prese..
The solvolysis product of 1-bromo-2,2-dimethylbutane with ethanol initially forms the expected carbocation but does not give any of the expected 1-ethoxy-2,2-dimethylbutane. Draw the rearranged cation that will eventually lead to the product.
explain the hazards associated with 1.0M CH3COOH solution, 0.10M BaCl2 solution and 0.10M Na2C2O4 solution.
If 2.61 g of methane gas (CH4) is introduced into an evacuated 1.67 L container at 15°C, what is the pressure in the container?
Calculate the amount of energy in the form of heat that is produced when a volume of 2.73 L of SO2(g) is converted to 2.73 L of SO3(g) according to this process at a constant pressure and temperature of 1.00 atm and 25.0 °C. Assume ideal gas behav..
