4. What is the Enthalpy value for the reaction in bold? Do not enter units.* 1 point Calculate Hyn for the reaction: 2 C(s) + H2(g) C,H,(9) CH2(g) + O2(g) 2002(g) + H2O(1) AH = -1300. C(s) + O2(g) + CO2(g) AH = -400 2H2(g) + O2(g) 2H2O(1) AH = -600 Your answer 5. What is the Enthalpy value for the reaction in bold? Do not enter units. * 1 point Calculate AHan for the reaction: C.H (9) + H(9) C.H (9), from the following data. CH, (g) + 3 02 (g) 2 CO2 (g) + 2 H20 (1) AH = -1400. 2 CH, (g) +70, (g) 400(g) + 6H20 (1) AH = -3000 H0 (1) H, (g) +12 02 (8) AH = +280. Your answer 6. What is the Enthalpy value for the reaction in bold? Do not enter units. Be 1 point careful this one is tricky. * H BO3(aq) HBO (aq) + H2O(1) H.B.0,(aq) + H2O(l) 4HBO (aq) H,B,0-(aq) H2O(l) + 2B,O3(s) AH = +250. AH = +300. AH = +200. Solve for AH n for the reaction 2H,BO, (aq) 3 H,O(1) + B,03(s). Your
