NaCl(aq) + AgNO3(aq) -----> AgCl(s) + NaNO3(aq) 33. Find the for the reaction below, given the following reactions and subsequent ΔH ΔH values: N2H4 (l) + CH4O(l) CH2O(g) + N2 (g) + 3H2 (g) → I. 2NH3 (g) N2H4 (l) + H2 (g) = 22.5 kJ → ΔH II. 2NH3 (g) N2 (g) + 3H2(g) = 57.5 kJ → ΔH III. CH2O(g) + H2 (g) CH4O(l) = 81.2 kJ → ΔH
