Calculate delta n (change in moles of gaseous substances) for each of the following balanced chemical
2c6h6o(l)+17o2−−> 12co2(g)+12h2o(l)
2so2(g)+o2(g)−−> 2so3(g)
n2(g)+o2(g)−−> 2no(g)
2na(s)+br2(l)−−> 2nabr(s)

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
