1.5 mol of oxygen are mixed with an unknown amount of nitrogen in a 2.0L container at a temperature of 26.0 degrees C. If the final pressure of the mixture is 4.3atm, what is the number of moles of nitrogen in the container. (Assume that both oxygen and nitrogen are perfect gases.)
the temperature of the solution increases to 26.5 C. Calculate the enthalpy change, Delta H, for this reaction per mole of X. Assume that the specific heat and density of the resulting solution are equal to those of water
