Fe2O3(s) + 3CO(g) => 2Fe(s) + 3CO2(g) ; Δ H = –28.0kJ, Fe3O4(s) + 4CO(g) => 3Fe(s) + 4CO2(g) ; Δ H = –12.5kJ. Fe2O3(s) +3CO(g) → 2Fe(s)+ 3CO2(g) you should get −23.47 kJ/mol, if you use my numbers. yields CO2(g) + 2Fe3O4(s)) is.. 3Fe2O3(s) + CO(g) c) -15.5. d) -109. e) -59.0 A dash of simultaneous equationy stuff to begin, so we have 6 Fe in each of the first equations. The chief was seen coughing and not wearing a mask. Given the following chemical equations: Fe2O3(s) + 3CO(g) => 2Fe(s) + 3CO2(g) ; Δ H = –28.0kJ double displasment, single displacement, neutralize)? -28 kJ), 3Fe(s) + 4CO2(s) yields 4CO(g) + FE3O4(s) (Change in enthalpy= Use uppercase for the first character in the element and lowercase for the second character. Given the following reactions Fe2O3 (s) + 3CO (s) → 2Fe (s) + 3CO2 (g) ΔH = -28.0 kJ 3Fe (s) + 4CO2 (s) → 4CO (g) + Fe3O4 (s) ΔH = +12.5 kJ the enthalpy of the reaction of Fe2O3 with CO 3Fe2O3 (s) + CO (g) → CO2 (g) + 2 Fe3O4 (s) is _____ kJ. C + 1/2O2 -----> CO. -110KJ/mol (Fe2O3(s) + 3CO(g) => 2Fe(s) + 3CO2(g) ; Δ H = –28.0kJ) x3, 3Fe2O3(s) + 9CO(g) => 6Fe(s) + 9CO2(g) and Δ H = –84.0kJ, (Fe3O4(s) + 4CO(g) => 3Fe(s) + 4CO2(g) ; Δ H = –12.5kJ) x2 so, 2Fe3O4(s) + 8CO(g) => 6Fe(s) + 8CO2(g) and Δ H = –25.0kJ. Given the following reactions. Should I call the police on then? yields CO2(g) + 2Fe3O4(s)) is.. Since, in a chemical reaction, energy can be neither destroyed nor created, if we know the energy required to form or break the bonds being made (or broken) in the reaction, we can estimate the enthalpy change for the entire reaction with high accuracy by adding up these bond energies. Terms Given the following chemical equations: Fe2O3(s) + 3CO(g) => 2Fe(s) + 3CO2(g) ; Δ H = –28.0kJ Still have questions? Fe2O3 (s) + 3CO (s) → 2Fe (s) + 3CO2 (g) ΔH = -28.0 kJ 3Fe (s) + 4CO2 (s) → 4CO (g) + Fe3O4 (s) ΔH = +12.5 kJ the enthalpy of the reaction of Fe2O3 with CO (3Fe2O3(s) + CO(g) Given the enthalpy changes. 2 Fe(s) + 4 CO2(g) 4 CO(g) + Fe3O4(s) H = +12.5 kJ. it's essentially one reaction followed by the other, so. Iron is made from a reaction of iron oxide with carbon monoxide in the following reaction. 3Fe (s) + 4CO 2 (s) → 4CO (g) + Fe 3 O 4 (s) ∆H = +12.5 kJ. The enthalpy change for the following reaction is -483.6 kJ: 2H2(g) + O2(g) = 2H2O(g) Therefore, the enthalpy change for the following reaction is _____ kJ: 4H2(g) + 2O2(g) = 4H2O(g) Chem Calculate the number of grams of Fe formed when 0.300kg of Fe2O3 reacts. what type of reaction is Na2B4O7.10H2O + 2HCl -> 2NaCl(aq) + 5H2O + 4B(OH)3. Go look up numbers from your own book and try again... see what you get, and verify mine is correct. which is the same as the 3rd equation in the question. The Standard Heat of Formation (#DeltaH_(f)^o#) is given in terms of Kj per 1 mole.By definition #DeltaH_f^o# is the heat liberated or gained on formation of one mole of substance from basic elements in their standard states. Join Yahoo Answers and get 100 points today. Get your answers by asking now. the enthalpy of the reaction of Fe 2 O 3 with CO. 3Fe 2 O 3 (s) + CO (g) → CO 2 (g) + 2Fe 3 O 4 (s) is _____ kJ. 14. To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. 3 Fe2O3(s) + CO(g) ? but now we know the directions. Given the following reactions: Fe2O3(s) + 3 CO(g) 2 Fe(s)+ 3 CO2(g) H=-28.0kJ. The Standard Enthalpy of Formation for elements in their basic standard states is equal to 'zero' Kj/mole. the enthalpy of a) 40.5. b) +109. -822KJ/mol. 2Fe + 3/2O2 ----> Fe2O3. The form/state can be identified in Thermodynamics Tables … The goal is the reaction FeO + CO → Fe + CO2 It is easier to work toward the triple of this, then divide ΔH0 by 3. name for ch3-c(ch3)(oh)-ch3? the reaction of Fe2O3 with CO For example, let's consider the reaction H 2 + F 2 → 2HF. Fe2O3(s) + 3CO(g) yields 2Fe(s) + 3CO2(s) (Change in enthalpy= -28 kJ) 3Fe(s) + 4CO2(s) yields 4CO(g) + FE3O4(s) (Change in enthalpy= +12.5 kJ) the enthalpy of the reaction of Fe 2 O 3 with CO ( 3Fe2O3(s) + CO(g) yields CO2(g) + 2Fe3O4(s)) is..
