Consider the copolymer structure: the polymer is a 9 carbon chain where carbons 1 and 9 have wavy lines representing further carbons not shown. Carbon 2 and 6 have chloro substituents, carbons 4 and 8 have methyl substituents. Draw the structures of the two alkene monomers used to form the copolymer.

0.2348 grams of pbcl2 used to form 44.0 ml of solution.

Which of the following contributes to the structural rigidity of cellulose? adjacent glucose polymers are stabilized by hydrogen bonding. glucose residues are joined by (α1→4) linkages. cellulose is a highly branched molecule. the conformation of the glucose polymer is a coiled structure.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
