Many ancient cultural statues and buildings were made out of marble. Marble is a type of rock which contains the metal calcium in it. Explain, using Table J, why marble statues are damaged by acid rain.

Acid rain can ruin buildings and statues by stripping away the material and corroding metal that makes up these structures. Architects chose limestone, marble, steel and brass as durable materials intended to resist the elements. But to their surprise, chemical reactions between the acid rain and building materials led to visible deterioration over time, dissolving structures like water does to a sugar cube.

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.
