Consider the following distribution of polymer chains:8 chains of degree of polymerization 1022 chains of degree of polymerization 10060 chains of degree of polymerization 50035 chains of degree of polymerization 10005 chains of degree of polymerization 50002 chains of degree of polymerization 50000A. Calculate the number and weight average degree of polymerization and polydispersity of this collection of polymer chains. B. If these chains were poly(vinyl alcohol), what are corresponding number and weight average molecular weights

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
