Draw the Caryophyllene (C15H24) structure and then show how it fits the "isoprene rule" by circling the 3 isoprene units in the structure.
Calculate the activation energy for creep for a low carbon-nickel alloy having steady state creep behavior. Using the data under a constant load:
a flask that can withstand an internal pressure of 2500 torr, but no more, is filled with a gas at 21.O C and 780 torr and heated. At what temperature will it burst?
What mass of sucrose should be combined with 453 of water to make a solution with an osmotic pressure of 8.00 at 320 ? (Assume the density of the solution to be equal to the density of the solvent.)
If the pressure exerted by ozone in the stratosphere is 3 x 10^-3 and the temperature is 247 , how many ozone molecules are in a liter?
The oil is burned with 20.0% excess air, based on complete combustion of the carbon to CO2, the hydrogen to H2O, and the sulfur to SO2. The oil is burned completely, but 8% of the carbon forms CO. Calculate the molar composition of the stack gas.
