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

Which of the following would be an accurate picture of the earth during the summer time of the northern hemisphere?

Which process transfers heat from inside earth to its surface? convection currents in mantle pulling away of tectonic plates drawing in of tectonic plates convection currents in crust

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
