Okay, well the first thing we need to understand with chemistry is something known as Reaction Rates. This is the amount of time it takes to complete a reaction.
Acidic Rain will not cause a building to instantly crumble or anything like that. Instead, calcium carbonate (which is chalk) will slowly break down due to acidity of the rain.
When something has a very high or very low ph, it is known to be corrosive. An example of a type of corrosion is the reaction between copper and oxygen to produce rust.
When Acidic Rain interacts with calcium carbonate, over time it will slowly start to degrade and break down. One thing you can compare it to is erosion.

Answer:
An x-ray detector, because x-rays are produced due to high energy collision of electrons
Explanation:
In order to check if metals are present in a given rock sample, different types of equipment are used. Example of such equipment is an x-ray detector. These x-rays are usually created when the direction of fast-moving electrons are changed as a result of their collision with a metal in a given rock sample. Thus, the best type of equipment that the metallurgical student could use to check if metals are present in a given rock sample is the x-ray detector.
