What is ΔG°rxn for 2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(l) ΔG°f(C2H6) = -33 kJ/mol; ΔG°f(CO2) = -394 kJ/mol; ΔG°f(H2O) = -237 kJ/mol ?
2C2H6 (g) + 7O2 (g) → 4CO2(g) + 6H2O (g) ΔH = -1560 kJ How much heat (in kJ) is released if 17.9 g of ethane ( 30.07 g/mol) undergoes combustion? (Give your answer as a positive number, since you cannot release negative energy.)
The combustion of ethane (C2H6) produces carbon dioxide and steam. 2C2H6(g)+7O2(g)⟶4CO2(g)+6H2O(g) How many moles of CO2 are produced when 5.45 mol of ethane is burned in an excess of oxygen? moles of CO2: mol

Consider the reaction 2C2H6(g) + 7O2(g)4CO2(g) + 6H2O(g) where S° rxn = 92.7 J/K Using standard thermodynamic data (in the Chemistry References), calculate the entropy change of the surroundings and the universe at 25°C. Ssurroundings = J K-1 mol-1 Suniverse = J K-1 mol-1
8. Find ∆H◦ of the reaction 2C2H6(g) + 7O2(g) = 4CO2(g) + 6H2O(g), as it is written, given the following: 2C(s) + 3H2(g) = C2H6(g), ∆H◦ = −84.68 kJ, 2H2(g) + O2(g) = 2H2O(g), ∆H◦ = −483.6 kJ, C(s) + O2(g) = CO2(g), ∆H◦ = −393.5 kJ. (A) −3194 kJ (B) −3109 kJ (C) −2940 kJ (D) −2855 kJ (E) −1428 kJ
Consider the exothermic reaction 2C2H6(g)+7O2(g)→4CO2(g)+6H2O(g) Calculate the standard heat of reaction, or ΔH∘rxn, for this reaction using the given data. Also consider that the standard enthalpy of the formation of elements in their pure form is considered to be zero. Reactant or product ΔH∘f (kJ/mol) C2H6(g) -84.7 CO2(g) -393.5 H2O(g) -241.8 Express your answer to four significant figures and include the appropriate units.
Consider the following balanced reaction: 2CH6(g) + 7O2 (g) ->4CO2(g) + 6H2O (g) How many liters of carbon dioxide at 300.0 degrees celcius and 10.0 atm are produced when 5.00 liters of C2H6 (g) are combusted at the same temperature and pressure. I have done something wrong, I get 2 L CO2 and then when I try again I get 9.54 L ov CO2 Thank you.
from the balanced equation 4NH3 +7O2 - 4NO2 + 6H2O. How many grams of oxygen are necessary to produce 4.50 moles of NO2? I think its 11 grams or 22 grams but im not sure. please help!! First the number of moles of O2, molesO2= (4/7) moles NO2 Notice those came from the balanced equation. Put in 4.5 moles NO2, and you have moles of O2. Grams of O2? multiply moles of O2 by 32. what do you mean I...
