CH (8) C($) + 4H(g) enthalpy of atomization of CH4 4x bond energy of C-H enthalpy of atom combination for CO2 enthalpy of combustion of CH4 enthalpy of formation of CO2(g) enthalpy of combustion of CH4 4x bond energy of C-H enthalpy of atom combination for CHA enthalpy of atomization of CH4 enthalpy of formation of C(g) 3. (graphite) + 2 H,(6) CH (8) 4. C(s) + 4H() CH (8) enthalpy of atomization of H2 enthalpy of atom combination for CHA I enthalpy of combustion of CH4 4 x bond energy of C-H enthalpy of formation of CH4(E) 4x bond energy of C-H enthalpy of atomization of CH4 enthalpy of atom combination for CH4 enthalpy of combustion of C enthalpy of formation of CH4(8)

Answer 1

1. CHA (g) + 202 (9) ► 00249) + 2H2011) 4H Xn = Enthalpy of combustion of CHA 2. CHACg) c(g) + 4H (9) . 4Hoxn = 4x bond energy of c-H | 3 (graphite) + 2 H2(g) → CHALG) Ahsxn = Enthalpy of formation of Chicg). E 4: C(g) + 4 H (9) CHALG). Hixn = Enthalpy of atom combination for CHA
