Q1 The balanced equation for the fomplete combustion of acetone(C3H6O) is: C3H6O + 4O2 --> 3CO2 + 3H2O  ΔrH-1790kJmol^-1 If a bottle of nail polish remover contains 177mL of avetone(density 0.788gmL^-1) how much heat is released by its complete combustion?   Q2. Draw the lewis structures for O-N-Cl and N-O-Cl. calculate the formal charges of the atoms and use these to determine which of these isomers is more stable.   Q3. The work function of aluminum is 412kJmol^-1. If light corresponding to 471kJ mol^-1 is shone on the metal what is the velocity of the electrons that are emitted from the metal?
