Question

Using these reactions, find the standard enthalpy change for the formation of 1 mol of PbO(s) from lead metal and oxygen gas:
PbO(s)+C(graphite)→Pb(s)+CO(g) ΔH°=106.8kJ
2C(graphite)+O₂(g) ΔH°=-221.0kJ
If 250 g of lead reacts with oxygen to form lead (II) oxide, what quantity of thermal energy (in kJ) is absorbed or evolved?
