Squalene is an important acyclic hydrocarbon whose molecular formula is C30H50. How many pi-bonds does squalene have. explain and show calculation
Calculate the systematic treatment of equilibrium. Remember C2O4^2- is a weak base so you must consider other equilibria. (Ksp(ZnC2O4)=7.5X10^-9, Kb1=1.8X10^-10, Kb2=1.8X10^-13). Solve using systematic treatment of equilibrium.
