An example of a polymer made from two different monomers is ?options are:-polthene, nylom, PCV, protein for complete oxidation, 1 mol of an organic compound requires 3 mol of oxygen gas. what could be the formula of the compound?

"Polymer is a term used to describe molecules consisting of structural units and a large number of repeating units connected by covalent chemical bonds. The key feature that distinguishes polymers from other molecules is the repetition of many identical, similar, or complementary molecular subunits in these chains. These subunits, the monomers, are small molecules of low to moderate molecular weight, and are linked to each other during a chemical reaction called polymerization."
That indicates to me that all polymers are made by combining two or more monomers.
"Copolymerization with two or more different monomers results in chains with varied properties.
A block copolymer is formed when the reaction is carried out in a stepwise manner, leading to a structure with long sequences or blocks of one monomer alternating with long sequences of the other.
There are also graft copolymers, in which entire chains of one kind (e.g., polystyrene) are made to grow out of the sides of chains of another kind.
The first commercially successful, completely synthetic polymer was nylon."
Biopolymers produced by living organisms include:
structural proteins: collagen, keratin, elastin…
chemically functional proteins: enzymes, hormones, transport proteins…
structural polysaccharides: cellulose, chitin…
storage polysaccharides: starch, glycogen…
nucleic acids: DNA, RNA
Synthetic polymers used for plastics — fibers, paints, building materials, furniture, mechanical parts, adhesives:
thermoplastics: polyethylene, Teflon polystyrene, polypropylene, polyester, polyurethane, polymethyl methacrylate, polyvinyl chloride, nylon, rayon, celluloid, silicone, fiberglass…
thermosetting plastics: vulcanized rubber, Bakelite, Kevlar, epoxy…"

it truly is the reason rescues stink. They by no skill supply human beings a wreck and maximum do not understand worry-free dogs practise. You by no skill introduce a clean dogs and picture it is going to paintings out each now and then it takes time. dogs stay in packs they could get alongside, only study some worry-free tips. look on youtube or google. Be comfortable and clam around the dogs have power of the chief. Be positive.
