Lead nitrate undergoes thermal decomposition according the following reaction.2Pb(NO3)2 (s) ⟶ 2PbO (s) + 4NO2 (g) + O2 (g) ΔH = 608 kJWhat is the ΔH for the reaction:6Pb(NO3)2 (s) ⟶ 6PbO (s) + 12NO2 (g) + 3O2 (g) ΔH=? kJ

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
