At 29 C the average rate is 3.3 flashes every 10 seconds;at 23 C the average rate falls to 2.7 flashes every 10 seconds. Calculate the activation energy for flashing process.
Compare the IR spectra of cinnamyl alcohol and cinnamaldehyde. What is the major difference
According to valence bond theory, the triple bond in ethyne (acetylene, C2H2) consists of A) three sigma bonds and no pi bonds B) two sigma bonds and one pi bond C one sigma bond and two pi bonds
What mass of H2O is required to form 1.3L of O2 at a temperature of 320K and a pressure of 0.957atm.
Correct the absorbance of the spiked samples for dilution and plot the absorbance versus ppm Fe added. Extrapolate the graph to the point where absorbance is equal to zero to determine the amount of Fe in the cat food sample in ppm.
Using the "like dissolves like" rule and the chemical structure of your unknown liquid, explain its solubility/insolubility in water. Describe the type of bonding that your unknown has (covalent, polar covalent)
A gas occupying a volume of 246 mL at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm.
Individual bonds in a molecule are often polar, molecules as a whole also often are polar because of the ne tsum of individual bond polarities. Which of the following molecules is/are polar? SF4, CCl4, C2H2.
