• Homopolymers and heteropolymers are two broad categories of polymers. The chemical and physical properties of these polymers may vary according to the monomers used in the production. The main difference between homopolymer and heteropolymer is that homopolymers are made from the polymerization of identical monomers whereas heteropolymers are made from the polymerization of two or more different monomers.Is protista a homopolymer or heteropolymerThe mass of electron is 9.8×10^-28gram and uncertainty in the velocity equal to 2×10^-3cm/second. The uncertainty in position of electron is (planks constant=(6.62×10^-27erg secondHNO3(aq)+ Cu(s)->NO2(g)+ Cu(NO3)2(aq)+ H2O(l)
