Suppose that each sphere represents 6.7×1021 molecules and that the volume of the container is 1.0 L. What is the rate constant for the reaction in the usual units? Express your answer to two significant figures and include the appropriate units show all steps
The element boron has two naturally occurring isotopes with masses of 10.0129 amu and 11.0093 amu. What is the percent abundance of the second isotope?
Colligative Porperties : Freezing Point Depression, Salt lowers the freezing point of water. So will sugar. If one tablespoon of solid (salt or sugar) is dissolved in ¼ cup of water
Ammonium Carbonate, NH4CO2, decomposes as follows: NH4CO2NH2(s) -> 2NH3(g) + CO2(g) Starting with only the solid, it is found that at 40C the total gas pressure is .363 atm. Calculate Kp.
If a reaction mixture contains only N2O and NO2 at partial pressures of 1.0 atm each, the reaction will be spontaneous until some NO forms in the mixture.
Benzene freezes at 5.45 oC. The Kf for benzene is - 5.07 oC/m. What would be the freezing point of a 0.210 m solution of octane in benzene?
