Zn+CuCl2 -> ZnCl2+Cu HCl+NaOH -> H2O+NaCl 2CO+O2 -> 2CO2 SO3+H2O -> H2SO4 . This reaction takes place at a temperature of over 500°C. The balanced equation will appear above. 9th - 12th grade. There are 0.800 mole of N2, 0.500 mole of O2, and 0.400 mole of NO in a 1.00-­‐liter container at 2870°C. Hint-2. but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. K= 2400 at 2000 K. If 0.61 g of NO are put in a previously empty 3.00 L. vessel, calculate the equilibrium concentrations of NO, N2, and O2. In presence of a catalyst the equilibrium is attained ten times faster. These tables, by convention, contain the half-cell potentials for reduction. [2ΔHf(NO (g))] - [1ΔHf(N2 (g)) + 1ΔHf(O2 (g))] O2 is more electronegative or more strong electron acceptor than N2.
