Go look up numbers from your own book and try again... see what you get, and verify mine is correct. 2 Fe(s) + 4 CO2(g) 4 CO(g) + Fe3O4(s) H = +12.5 kJ. & The goal is the reaction FeO + CO → Fe + CO2 It is easier to work toward the triple of this, then divide ΔH0 by 3. Use uppercase for the first character in the element and lowercase for the second character. Calculate the enthalpy of the reaction of Fe2O3(s) with CO(g) (in kJ). 3 Fe2O3(s) + CO(g) ? Given the following chemical equations: Fe2O3(s) + 3CO(g) => 2Fe(s) + 3CO2(g) ; Δ H = –28.0kJ double displasment, single displacement, neutralize)? yields CO2(g) + 2Fe3O4(s)) is.. 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 A dash of simultaneous equationy stuff to begin, so we have 6 Fe in each of the first equations. it's essentially one reaction followed by the other, so. 1 Answer to Given the following reactions: 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.. A. -28 kJ), 3Fe(s) + 4CO2(s) yields 4CO(g) + FE3O4(s) (Change in enthalpy= Iron is made from a reaction of iron oxide with carbon monoxide in the following reaction. help needed for organic chem MC question? The chief was seen coughing and not wearing a mask. C + 1/2O2 -----> CO. -110KJ/mol the reaction of Fe2O3 with CO | but now we know the directions. Well, when you manage to search your appendix for the … Join Yahoo Answers and get 100 points today. 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. Should I call the police on then? Privacy Given the following reactions: Fe2O3(s) + 3 CO(g) 2 Fe(s)+ 3 CO2(g) H=-28.0kJ. the enthalpy of -822KJ/mol. name for ch3-c(ch3)(oh)-ch3? As the top equation keeps its original direction, Δ H keeps its sign. We know 3Fe2O3(s) is our starting product so the top reaction occurs in its original direction, and the other is reversed. That is: work towards 3 FeO + 3 CO → 3Fe + 3 CO2 . A) -59.0 I know the answer is -59 but I do not know how you work it out to find that answer. Fe2O3(s) + 3CO(g) => 2Fe(s) + 3CO2(g) ; Δ H = –28.0kJ, Fe3O4(s) + 4CO(g) => 3Fe(s) + 4CO2(g) ; Δ H = –12.5kJ. Consider the following intermediate chemical equations. -109 kJ B. what type of reaction is Na2B4O7.10H2O + 2HCl -> 2NaCl(aq) + 5H2O + 4B(OH)3. For example, let's consider the reaction H 2 + F 2 → 2HF. +12.5 kJ). 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. Get your answers by asking now. (3Fe2O3(s) + CO(g) Terms Given the enthalpy changes. The form/state can be identified in Thermodynamics Tables … Iron is made from a reaction of iron oxide with carbon monoxide in the following reaction. I went to a Thanksgiving dinner with over 100 guests. c) -15.5. d) -109. e) -59.0 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.. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. 14. Still have questions? The Standard Enthalpy of Formation for elements in their basic standard states is equal to 'zero' Kj/mole. According to Hess's law, if a series of intermediate reactions are combined, the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
