An organic lab has synthesized a new compound made of C, H, and N. You are asked to characterize this material.
MW of substance: 110.18 g/mol
A pure amount of this substance was then heated in a closed containe until the liquid-gas interface disappeared. The pressure and temperature at this point was 15.2 MPa and 315 K. Calculate the Van der Waals coefficients and the Virial coefficients for this compound.
The reaction 2A + B --> C + D has an activation energy of 80.0 kJ/mol. At 320°C, the rate constant k = 1.80 x 10-2 L mol-1 s-1. What would be the value of k at 450°C?
The partial molar volumes of water and ethanol in a solution with x(H2O) = 0.40 at 25 degrees C are 16.9 and 57.5 cm^3/mol, respectively.
A solution containing 100 g of an unknown liquid and 900 g water has a freezing point of - 3.33 oC. What is the molar mass of the liquid? Kf = 1.86oC/m
Calculate the amount of heat required to raise the temperature of 100.0g of water from -0.10 C to +0.10 C
sulfuric acid acts as a catalyst for making esters. Write an equation showing the production of Isoamyl alcohol
Suppose Joule encountered the waterfall at Niagara Falls. Calculate the height if the temperature difference between the top and bottom of the waterfall is 0.20° F.
The equilibrium constant for a certain reaction decreases from 8.91 to 3.5 10-2 when the temperature increases from 29°C to 73°C. Estimate the temperature where K = 1.00 for this reaction.
Calculate the minimum mass of hydrochloric acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.
Do you think you could distinguish between 3-methylcyclohexene and methylenecyclohexane by their GC retention times?
The spectrum exhibited an absorption band at 260 nm which is attrbutable to benzene, and the absorbance of this band was 0.69. In a reference source, the student found that the molar absorptivity of this benzene band in ethanol
a sample of gas occupies a volume of 400 ml at 0.740 atm and 70 oc. calculate the pressure of the gas if its volume is
