Mixed Practice: For questions 6-9, you may not have to use your entire flow chart. Decide where to start and end using your flow chart.

4NH3 + 5O2 → 4NO + 6H2O

MM NH3 = 17.04 g/mol; MM O2 = 32 g/mol; MM NO = 30.01 g/mol; MM H2O = 18.02 g/mol

In the above reaction, how many moles of NO are formed if 824 g of NH3 react?

27.5 mol
3510 mol
48.4 mol
774 mol

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
