my answer is wrong please help Calculate AHan for the following reaction: BaO(s) + CO2(g) → BaCO3(s) Use the following reactions and the given values of AH for them: Ba(s) + CO2(g) + O2(g) → BaCO3(8), AH = -826.5 kJ 2Ba(s) + O2(g) + 2BaO(s), AH = -1184.0 kJ Express your answer to four significant figures in kilojoules. ► View Available Hint(s) IO AD * * O2 ? AH.= 269.0
(Please explain) Hess Law delta H Manipulate the data provided to find the ΔHrxnfor the reaction: CH4(s) + 2 O2(g) →CO2(g)+ 2 H2O(l) (1) 2 CH4(g)+ 3 O2(g) →2 CO(g) + 4 H2O (l) ΔH= −1215 kJ (2) 2C + O2(g) →2 CO(g) ΔH= −221 kJ (3) C (s) + O2(g) → CO2(g) ΔH= −394 kJ I have solved it myself but I am not sure of the answer I have gotten. my answer was about -228.5kj
The direct reaction of methane (CH) with oxygen to give carbon monoxide is hard to accomplish without also producing carbon dioxide. However, we can use a Hess's law calculation to calculate AH,anyway. Calculate AH in kJ for the following reaction from the thermochemical equations given. 35. 2CO(g) + 4H2O() 2CH&(g) +302(g) Use the following thermochemical equations: AH-221.08 kJ 2CO(g) (1) 2C(s)+O2(g) AH=-890.4 kJ CH&g)+202(g) CO2(g)+ 2H20() (2) AH -393.51 kJ CO2(g) C(s)+O2(g) (3)
5. Use the following data to determine the delta H for the conversion of diamond into graphite: C(diamind) (s) + O2(g) = CO2(g) delta H degrees = -395.4 kJ 2CO2(g) = 2 CO(g) + O2(g) delta H degrees = 566.0 kJ 2CO(g) = C(graphite) (s) + CO2 (g) delta H degrees = -172.5 kJ C(diamond) (s) = C(graphite) delta H degrees = ?
DaC. NUL20 1) Find AH, for the reaction 2H2(g) + 2C(s) + O2(g) → C2H5OH(I), using the following thermochemical data. For Hess's Law, rewrite equations to find out AH. C2H5OH (1) +2 02 (g) → 2 CO2 (g) + 3H20 (1) AH = -875.J C(s) + O2(g) → CO2 (g) AH = -394,51 kJ H2(g) + 12 02 (g) → H20 (1) AH = -285.8 kJ
