<p>The first thing you sXXXXX do XX XX XXXXX out the XXXXXXXX XXXXXXXX XXXXXXXX XXX the reaction of interest. This XX:</p> <p>XXXX(g) + 3O2(g) --&XX; XXX(g) + 6H2O(g)</p> <p>XXXX, you need to XXXX XXX enthalpy of formation XX each of the XXXXXXXXX in XXX XXXXXXX. Only one XX these XX given in XXX question: NH3(g). You XXXX to XXXX up XXX XXXXXX; XXXXX XXXXXX XX XXXXX in kJ/mol.</p> <p>Once you XXXX XXX XXX numbers, the XXXXXXXX XXXXXX of XXX reaction XX:</p> <p>X*Ef[XX(g)] + X*Ef[XXX(g)] - 4*XX[NH3(g)] - X*XX[XX(g)] XXXXX Ef denotes XXX XXXXXXXX XX formation of XXX XXXXXXXX in XX/mol.</p> <p>Okay, so XXXX you XXXX XX know how XXXX XXXXX of XXX XXXXX are in XX. That's why the density XX XXXXX. XXX can use mass = XXXXXXX*XXXXXX to get XXX number XX XXXXX of XXX XXXXXXXXXX to XX of XXXXXX.</p> <p>XXXX you have that, XXXX out XXX molecular weight of XXX (in g/XXX) and XXX that to work out how XXXX XXXXX XX NH3 you XXX reacting.</p> <p>Finally, you XXXX from XXXXX what enthalpy change is produced XX X XXXXX of XXX(g), so divide XXXXXX by 4 XXX multiply it by the number XX XXXXX of XXX you actually have. This XXXX give you the XXXXXXXX XXXXXX XXX the XXXXXXXX XXXXXXXX being XXXXXXX out.</p> <p>XXXX that XXXXXX!</p>">
