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.

At a certain temperature it is found that {NB} moles of NOBr, {NO} moles of NO and {Br} moles of Br2 are in equilibrium in a {V} L container according to the reaction below. What is the equilibrium constant? 2 NOBr (g) ⇌ 2 NO (g) + Br2 (g) Keep extra significant figures during the calculation and round your answer to 2 decimal places.

What are some of the advantages of using a configuration management system, such as svn, versus not using a configuration management system? Write the svn command from your current working directory to obtain the latest versions of the files in a repository that other users have updated. Afterwards, write the svn command to update the repository to contain the latest versions of your files in your current directory that you have modified. You can assume for both svn commands that the repository has already been created and checked out in your current directory.
