what volume of hydrogen gas is produced when 1.40 mol of carbon monoxide reacts completely according to the following
Is there enough info to calculate the pressure of gas if the barometric pressure is 755 torr and if so what is the answer
An experiment shows that a 248mL gas sample has a mass of 0.433g at a pressure of 745 mmHg and a temperature of 28 degrees C. What is the molar mass of the gas
A sample of (S)-2-butanol has an observed rotation of +1.03°. The measurement was made with a 1.0 M solution of (S)-2-butanol in a sample container that is 10 cm long. What is the specific rotation [?]D, for (S)-2-butanol
Describe how you will prepare a H2PO4-/HPO42- buffer using solid sodium dihydrogen phosphate and sodium hydrogen phosphate (pH 7.4, 500 mL 0.40M each).
In an adiabatic compression if one mole of an ideal gas with a Cv=5R/2, the temperature rises from 293 K to 325 K. Calculate the heat, work, change in enthalpy and change in internal energy
A sample of oxygen gas has a volume of 150 mL when its pressure is 0.947 atm. What will the volume of the gas be at a pressure if 0.987 atm if the temputure remains constant
The diameter of the laser beam is 5.5 mm. If the laser is pointed toward a pinhole with a diameter of 1.2 mm, how many photons will travel through the pinhole per second?
Consider the hypothetical reaction A 2B, for which ?Go is -16.6 kJ/mol. In a certain experiment, the initial concentrations are [A] = 8.00×10-3 M and [B] = 2.500 M at a temperature of 298 K. Calculate G for the reaction at these concentrations.
E was found to be -2,000.00 kJ/mol of an unknown liquid hydrocarbon at 298 K. In another experiment it was determined that for each mole of hydrocarbon, 5 moles of oxygen gas are consumed
