What i volume of oxygen is required for the complete combustion of 15cm3 of ethnic (C2H6) if all gases are measured at S. T.P , what is the total volume of the products of the reaction 2 C2H6 + 7O2 = 4CO2 + 6H2O ?

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
