Question: What is the MOLAR heat of combustion of benzene, C6H6, if the combustion of 1.00g of BENZENE CAUSES THE TEMPERATURE RISE OF 5.18 deg C in a bomb calorimter that has a heat capacity of 8.07 kj/deg C? (molar mass c6h6 = 78.1)
What is the standard enthalpy of combustion of propene. Note that since this is the standard enthalpy, carbon dioxide will be gaseous and water will be a liquid.
a) Draw the product of the reaction of propanal with lithium aluminum hydride, followed by water. b) Draw the product of the reaction of propanal with methylmagnesium iodide, followed by dilute acid
How much heat is required to raise the temperature of a mole of oxygen from 298 to 3000 K at constant pressure. The book gives the following values for Cp (specific heat at constant pressure): 29.376 J/(K*mol) at 298 K and 39.884 J/(K*mol) at 3000 ..
If it takes 4.67 times as long for a particular gas to effuse as it takes hydrogen under the same conditions, what is the molecular mass of the gas?
200.0 mL flask containing 1.03 mg and 0.56 mg O2 I have a 15 * C to calculate the partial pressures of oxygen and helium in a flask. which is the total pressure
how many grams of lithium bromide must be added to 35 grams of water to make a solution
how many heat energy is required to heat a cup of water (195.0) from room temperature (25.0C) to boiling (100.0C).
Calculate the vapor pressure of water, in torr, above a solution prepared by dissolving 65.40 g of ZnCl2 in 445.0 g of water at 323.0 K. The vapor pressure of pure water at 323.0 K is 92.50 torr.
The vapor pressure and enthalpy of vaporization of an unknown substance are measured to be 204.2 torr and 28.8 kJ/mol, respectively at room temperature (298.15 K). Estimate the normal boiling point of the substance at an atmospheric pressure of 76..
Calculate standerd enthalpy of formation for dimand given that C graphite + oxygen(g) -------CO2(g) H = -393,5kj/m dimond(C) + O2(g)------CO2 (g) H = -395.1kj/m
What is the order with respect to OH ^-1 for this reaction. The answer is 2 and the solution is 2^X = 4 ; X=2. Do I do this with every rate reaction problem.
