Use a standard enthalpies of formation table to determine the change in enthalpy for this reaction. 2 NO(g) + O2(g) ---> 2 NO2(g) ΔΗ = Σ(nΔΗ°f products) - Σ(nΔΗ°f reactants) = [2(AHF of NO2(g))] - [2(AHºr of NO(g)) + (AHºr of O2(g)]​

Ethanol (c2h5oh) is produced from the fermentation of sucrose in the presence of enzymes. c12h22o11(aq) + h2o(g) 4 c2h5oh(l) + 4 co2(g) determine the theoretical yield and the percent yields of ethanol if 680. g sucrose undergoes fermentation and 326.5 g ethanol is obtained. theoretical _ g _ percent %
