Using the standard enthalpies of formation, what is the standard enthalpy of reaction?
co(g)+h2o(g)⟶co2(g)+h2(g)
the formation values are as follows:
δhf (co(g)) = −110.525kj/mol
δhf (co2(g)) = −393.509kj/mol
δhf (h2o(g)) = −241.818kj/mol
δhf (h2(g)) = 0

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
