Why is permeable soil best for plants that need a lot of drainage? a Water fills this type of soil. b Water dries up in this type of soil. c Water flows through this type of soil. Water pools on top of this type of soil. subject science

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.
