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)]​

Animals that reproduce sexually either do it through external or internal fertilization. read the following statement and decide if it is true or false. birds reproduce through external reproduction which is because the female will then be able to protect the egg.
