Based on the following chemical equation: 4HCN 5O2 2N2 4CO2 2H2O. Identify the limiting reactant and the mass of N2 produced when 100. g of HCN react with 100. g of O2. g

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.
