Given these reactions, where X represents a generic metal ormetalloid
1) H2(g)+12O2(g)⟶H2O(g)Δ𝐻1=−241.8 kJ
2) X(s)+2Cl2(g)⟶XCl4(s)Δ𝐻2=+143.9 kJ
3) 12H2(g)+12Cl2(g)⟶HCl(g)Δ𝐻3=−92.3 kJ
4) X(s)+O2(g)⟶XO2(s)Δ𝐻4=−860.9 kJ
5) H2O(g)⟶H2O(l)Δ𝐻5=−44.0 kJ
what is the enthalpy, Δ𝐻, for this reaction?
XCl4(s)+2H2O(l)⟶XO2(s)+4HCl(g)
