For the following monomers: i) draw the polymer resulting from their polymerization using dash structures, but you can abbreviate repeats and h’s as i did in the monomers. be sure to show the repeat unit in parentheses; ii) show any by-products (i. e. leaving groups); and iii) indicate if they polymerize via a condensation or free radical addition reaction (you can abbreviate with c or fra written above the reaction arrow).

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

hope this !

and sorry if i'm late. have a good rest of your day! : d
