While a single alkene monomer, such as ethylene, is polymerized, the product is a homopolymer. If a mixture of two alkene monomers is polymerized, but a copolymer often results. The subsequent structure represents a segment of a copolymer.
Depict the structures of the two monomers that were copolymerized to form the copolymer.
Take 7 test tubes from the Glassware shelf and place them on the workbench. Add 1g of the seven metals on the chemicals shelf (Ag, Ca, Cu, Fe, Mg, Pb, Zn) into the seven test tubes, one metal per test tube.
Consider the following reaction at equilibrium. what effect will increasing the volume of the reaction mixture have on the system?
