b. compund chemical decomposition requires chemical processes

c. mixture physical youre, if you boil it, you can seperate the sugar

Answer 2

physical changes CAN be reversed. Chemical Changes CANNOT be reversed.

When looking for chemical, always try to find words like decompose, combust, oxidized.

In this case, "a" and "c' are physical since they can be easily reversed back to originals. "b" is chemical because after decoposition occurs, the original is gone forever.
