a)Write a balanced chemical equation that describes the combustion of one mol of oxalic acid. (C2H2O4(s)) b)Write a balanced chemical equation that describes the standard formation of oxalic acid. c) -------- d)Calculate deltaS(Jmol^-1K^-1) for oxalic acid and delta S (Jmol^-1K^-1) for the combustion of one mole of oxalic acid. (Note: absolute entropy, S, for oxalic acid is 120.1 J mol^-1K^-1). e)Calculate deltaG(kJmol^-1) for oxalic acid and delta G (kJmol^-1) for the combustion of one mole of oxalic acid.
