Give the formula of the conjugate acid of H2O.

Give the formula of the conjugate base of H2PO4–.

Calculate the equilibrium composition for the reaction when the ratio of H2+1/2 O2<=> H2O  the number of moles of elemental hydrogen to elemental oxygen is unity. The temperature is 2000 K, and the pressure is 1 atm.-------------------------------Some tables attachedFrom table information:O2: T = 2000 Kcp = 37.788 kJ / kmol-K(ho (T) hfo (298)) = 59,169 kJ / kmol hfo (T) = 0 kJ / kmol so (T) = 268.656 kJ / kmol-K gfo(T) = 0 kJ / kmol

Using enthalpies of formation, calculate AHrxn for the reaction: C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(()
