Describe the various cons of eating the organic foods? Briefly illustrate it.
Two tanks which contain water are connected to each other through a valve. The initial conditions are as shown (at equilibrium):
These types of polymers are formed as a result of condensation reaction between monomer units. Some common examples are being discussed here: 1. Polyesters Q : What is solvent dielectric effect? Ionic dissociation depends on the dielectric constant of the solvent.The Arrhenius that ions are in aqueous solutions in equilibrium with parent molecular species allows many of the properties of ionic solutions to be understood. But difficulties began to
