An equilibrium mixture contains 0.650 mol of each of the products (carbon dioxide and hydrogen gas) and 0.200 mol of each of the reactants (carbon monoxide and water vapor) in a 1.00-L container.
CO(g) +H20 (g) --> <-- CO2 (g) + H2 (g)
How many moles of carbon dioxide would have to be added at constant temperature and volume to increase the amount of carbon monoxide to 0.300 mol once equilibrium has been reestablished?
At 0.0oC, if the volume of air is 3.3 mL and the pressure of the atmosphere that day is 835 mmHg, what is the number of moles of air?
Explain how some solids (compounds that are solids at room temperature) can be analyzed by gas chromatography. Also, how can they be introduced into the injector port and column
For each of the following strong base solutions, determine [OH-], [H3O+], pH and pOH. a) 0.14 M NaOH? b) 1.7x10^-3 M Ca(OH)2? c) 4.5x10^-4 M Sr(OH)2? d) 8.6x10^-5 M KOH
An herbicide is found to contain only C, H, N, and Cl. The complete combustion of a 100.0-mg sample of the herbicide in excess oxygen produces 83.16 mL of CO2 and 73.30 mL of H2O vapor at STP. A separate analysis shows that the sample also contain..
calculate the change in entropy (?S), the change in internal energy (?U), and the change in enthalpy (?H) for a reversible adiabatic expansion of this gas to a final pressure of 1.10 atm. Also calculate the final temperature (T) and volume (V).
A sample of hydgrogen gas, H2, has a volume of 8.56L at a temperature 0C and a pressure of 1.5 atm. Assuming the gas behaves ideally: how many moles of H2 are present in this gas sample
You are tasked with preparing 100 mL of a pH = 12.00 buffer. Each buffer component must have a concentration of at least 0.10 M.
use maxwell distribution of speeds to estimate the fraction of CO2 molecules at 300K that have speeds in the range 200 to 250 m/s.
What is effective diffusion coefficient of CH4 in the nanochannel at the feed gas conditions? Is Knudsen diffusion important?
Explain in terms of noncovalent interactions why water and ethanol are miscible, but water and cyclohexane are not.
A sample of neon gas is held in a rigid 1.814L container with a pressure of 1.273atm at 25 C. 3.193g of an unknown gas is added to the container. The temperature remains constant, but the pressure rises to 2.386atm. What is the molar mass of the a..
If the quantum number ms had possible values ±1, ±2, what would be the maximum number of electrons that be placed in a single orbital
