2 NO(g) + Br2(g) reverse reaction arrow 2 NOBr(g)
What would be the partial pressures of all the species if NO and Br2, both at an initial pressure of 0.30 atm, were allowed to come to equilibrium at this temperature?
the density of aluminum is 2.70 gm/cm3 the density of chromium is 7.19 gm/cm3. if equal masses of Al and Cr are addede to equal vol of H2O in separate graduate cylinder which would have the greatest change in volume
if 32.5 grams of cao are dissolved in 212 grams of water what is the concentration of the solution in percent by
Explain the effect of the following experimental errors on your results: a) You add hexane to the reaction flask instead of 1-hexene b) You use 3% hydrogen peroxide instead of 30% c) You forget to add potassium carbonate in the seperation step.
A 295 mL stock solution contains 2.3 M Ca(CN)2. When 100 mL of the stock solution is diluted to 120 mL, how many moles of CN- ions will be contained in the dilute solution?
Calculate the volume occupied by 1.00 mol N2 using the van der Waals equation in the form of a virial expansion at (a) its critical temperature, (b) its Boyle temperature, and (c) its inversion temperature
A solution containing 3.47mM X (analyte) and 1.72 mM S (standard) gave peak areas of 3473 and 10222, respectively, in a chromatographic analysis. Then 1.00ml of 8.47mM S was added to 5.00ml of unknown X, and the mixture was diluted to 10.0ml. This..
