The equilibrium concentrations in a 10.00-L rigid container are [H₂] = 0.0600 M, [F₂] = 0.0200 M, and [HF] = 0.620 M. If 0.350 moles of F₂ is added to the equilibrium mixture, calculate the concentration of H₂ after equilibrium is reestablished.

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed

The bond energy for the van der waals bond between two helium atoms is 7.9×10−4ev. assuming that the average kinetic energy of a helium atom is (3/2)kbt, at what temperature is the average kinetic energy equal to the bond energy between two helium atoms

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.
