2 H2 (g) + O2(g) → 2 H2O (g). 42NH3. → 242 +0XT. AH = -180.5 kJ. AH-91.8 kJ. AH ... Find AH° for the reaction 2H2(g) +2C(s) + O2(g) → C2H5OH(1), using ... Since there is an equal number of each element in the reactants and products of (2H2) + O2 = (2H2O), the equation is balanced. The △ S for the reaction: 2H2 +O2 =2H2O at 300k when SH2=126.6, SO2=201.20, SH2O=68.0JKmol ... →2H2O+3S. Q. For the series of reactions given below : 2H2 ... Mar 1, 2021 ... The equation shows that: 2 moles of H2 react with 1 mole of O2 in this equation (that is what the numbers in front of the formulae mean) and produce 2 moles of ... Oct 1, 2020 ... 2H2O2(aq) → 2H2O(l) + O2(g) The graph (Figure 1) shows the concentration of H2O2 as a function of time. Use the graph to calculate the following. 2H2O2 → 2H2O + O+. 2 + 4e−. (3) is promoted by applying a potential to the electrochemical cell. Cytochrome P450 (CYP) belongs to a family of heme proteins ... CuC2O4 → CuO + CO +CO2 240 °C. Step 2. CuO → Cu2O + ½ O2. 800 °C.
