An evaluation of R was performed, following the procedure described in this module. The barometric pressure was 736 torr, the temperature was 295k and volume of hydrogen gas collected was 35.6 mL. The calculated value of R was 82.1 mL atm K^-1 mol^-1.
1. If the vapor pressure of water had not been taken into account, what would have been the calculated value of R?
How many grams of CO2 were used during the month? molar mass of CO2 is 44.00995 g/mol.
What are the other side products present in this biocatytic reaction?
A buffer solution containing 0.25 M Acetic acid and 0.56 m Sodium acetate. After addition of 0.0060 mol HCL what is Ph of buffer.
Draw the major organic product formed when toluene reacts with nitric acid in the presence
Which resonance structure for the SCN- ion and the COS molecule would you expect to be more stable
a 150.0 g sample of metal at 80 c is added to 1500.0g of H2O at 20 c. the temperature rises to 23.3 c. assuming that the calorimeter is a perfect insulator, what is the specific heat of the metal.
A piece of metal of mass 18 g at 117 C is placed in a calorimeter containing 48.2 g ofwater at 21C. The final temperature of the mixture is 85.4C.
At the end of the process, the pressure is 2.50x10 to the 6 Pa. Calculate the final temperature of the gas. Calculate q, w, deltaU, and deltaH for this process.
Lithium will react with oxygen in a pressurized container to produce solid lithium oxide at 25°C. if 0.130 g Li(s) is placed in a 0.500 L container filled with oxygen at 1.90 atm
in a strongly acidic solution the amino acid lysine esists as the dication. as the pH is raised, what monocation is formed by the loss of a proton form the dication?
Calculate the resulting pH if 365 mL of 2.88 M HNO3 is mixed with 335 mL of 1.10 M Ca(OH)2 solution.
Starting with the standard free energies of formation from the following table calculate the values of delta G° and E° cell of the following reactions:
