Determine if the following two structures are identical, isomers, or unrelated?
CH
CH3
CH3
CH,
B
С
identical
isomers
unrelated

             Identical

Explanation:

                   Both compounds are identical. If you rotate the compound on the left 60 degree anticlockwise you will get the compound on the right.

                   These are not isomers of each other because they have same structural and molecular formulas.

                   Also, they are related to each other because they are the same

idk

explanation:

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.
