Jake is creating a project with an electric circuit. For part of the project, Jake needs an insulator. A good insulator would NOT be made of which of the following? Group of answer choices

Plastic

Rubber

Copper

Glass

plastic

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.

so what is the problem with your lab report and whats the subject of the lab report? i will you
