A certain third order reaction has a rate of {r1} M/s when the concentration of reactant A is 0.30 M. What is the rate for this reaction of the concentration of A is 0.60 M? Report your answer to three decimal places.

What is the pH of a {M} M solution of ammonium bromide? Report your answer to 2 decimal places. Kb of NH3 = 1.8×10-5

At a certain temperature, the solubility of zinc(I) chromate is {M} M. What is the Ksp? Report your answer to 2 sig figs.

Using the standard enthalpies of formation Hf0 given and your knowledge of Hf0 values for elements in their standard states, determine the enthalpy of this reaction. Assume that O2 (g) does represent oxygen. 2A3X2 (g) + O2 (g) → 2A3X (g) + 2XO (g) Hf0 values  A3X2 (g) = –{C2} kJ/mol A3X (g) = –{CO} kJ/mol XO (g) =  {NO} kJ/mol For full credit: Round your answer to the ones place so that there are no decimals.  (EX:  12.3 = 12) Include the correct unit.
