When monomers a and b are copolymerized, an azeotrope (polymer composition same as feed) is formed at a ratio of 7 mol of a to 3 mol of b. if monomer b is known not to homopolymerize, (a) what polymer composition (mole fraction of a) will result initially when a mixture of 9 mol of a and 1 mol of b is polymerized? (b) will polymer formed after 50% conversion from an initial mixture of 4 mol of a and 6 mol of b contain more a than polymer formed at 1% conversion? less a than polymer formed at 1% conversion? 3 1 2 same fraction of a as polymer formed at 1% conversion?

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.      

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
