Ethane gas at 140 F is burned in a steady-flow process with theoretical air at 40 F in such a way that the products are at 840 F.
(a) Write down the balanced chemical equation for one lbmol of ethane
(b) Find the heat transfer in Btu per lbmol of ethane.
Use the octet rule to predict the formula of the simplest compound formed from hydrogen and selenium. Why
The Kc for the reaction of hydrogen and iodine to produce hydrogen iodide equals 54.3 at 430 C. Calculate the quilibrium concentrations of H2,I2, and HI if the intial concentrations are H2=I2=0M and HI=.525M.
A) How many O2 molecules are needed to react with 6.09 of S? B) What is the theoretical yield of SO3 produced by the quantities described in Part A?
Calculate the pH during the titration of 20.00 mL of 0.1000 M C6H5COOH(aq) with 0.1000 M NaOH(aq) after 19.54 mL of the base have been added. Ka of benzoic acid = 6.5 x 10-5.
what are the structures for glycylserine and
At 100 C the equilibrium constant for the reaction COCl2(g) ?? CO(g) + Cl2(g) has a value of Kc = 2.19 X 10 ^-10. Are the following mixtures of COCl2, CO, and Cl2 at 100 C at equilibrium? If not, indicate the direction that the reaction must proce..
At a temperature T, a previously empty 5.00L flask is prepared by adding 1.20 mol SO2 and 1.5 mol of O2. Determine the concentrations of SO2, O2 and SO3 once equilibrium is established. KC=963
If the pressure of "wet" hydrogen is assumed to equal atmospheric pressure and the volume is recorded, will the calculated moles of hydrogen gas be too high or too low?
After carrying out the reaction, why does a precipitate (solid) form when you pour the reaction mixture on ice
The density of pure silver is 10.5 g/cm3 at 20°C. If 5.25 g of pure silver pellets is added to a graduated cylinder containing 16.1 mL of water, to what volume level will the water in the cylinder rise
what is the volume of 235 ml of a sample of gas at 53.0degc and 740. mm hg if the conditions are adjusted to stp?
