Explain how alkene/aromatic C-H stretches are distinguished from alkane C-H stretches. Do the C-H stretch peaks in the IR spectra of triphenylmethanol, bromobenzene and benzophenone occur in the expected alkene/aromatic C-H stretching region
The equilibrium constant for this reaction is Keq=4 at 110C. In a certain experiment, .6 moles each of water vapor and carbon monoxide are introduced into a 2 Liter vessel at 110C
calculate the enthalpy change for an isobraic change of steam from 0.8 MPa and 250 C to saturated liquid
How would the absorbance of a NaSCN have been affected if .30 M Fe(NO3)3 had been used in place of .20 M? (In the case that the reaction has been completely driven to FeSCN2+
if 1.205 g of KHP required 25.25 mL of NaOH solution for complete neutralization, what is the molarity of the NaOH sodium hydroxide solution?
At 650K MgCO3(s)(----)MgO(s)+CO2(g) has Kp=0.026. A 10L container at 650K has 1.0 g of MgO(s) and CO2 at P=0.0260 atm. The containeer is than compressed to a volume of 0.100L. Find the mass of MgCO3 that is formed
How much heat would be released if 12.0 g of methane, CH4, was completely burned in oxygen to form carbon dioxide and water at standard state conditions
What two atomic orbitals or hybrid atomic orbitals overlap to form the CC bond in ethylene
A sample of natural gas at STP is 78% CH4 and 22% C2H6 by volume. How many moles of each gas are present in 2.00 L of the mixture. Assume Ideal gas behavior.
Draw isotherms generated by this equation which are at the critical temperature, above the critical temperature, and below the critical temperature. Also, mark on the sketch the critical volume and the critical pressure for the gas.
For a general reaction order n, determine the rate equation, the variables to be plotted to obtain a graph with a linear slope equal to the rate constant k (or -k), and an expression for the ½ life
