A gold cylinder has a height of 5.5 cm. The density for gold is 19.3 g/cm^3. The mass of the cylinder is 25.5 grams. Determine the volume and radius of the cylinder. (Hint: Volume of cylinder is V = pie*r^2*h) *

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.

b.

the accuracy of the data.
