Will mark jimmy weighs himself three times using the same bathroom scale. each measurement yields the same result, but jimmy is confident that the measurements do not reflect his true weight. which of the following statements most likely describes the scale.

a. the scales's measurement's are accurate and precise.
b. the scale's measurement's are accurate but not precise.
c. the scale's measurement's are precise but not accurate.
d. the scale's measurement's are neither accurate nor precise.

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.
