Answer:
Alchemy was scientific, because it included observations and experiments

Scientific research is one that is done through a series not steps or methods. Observation and experiments are part of the steps in a scientific research.
Scientific research is done through investigation of various theories of science as well as formulating hypothesis. Scientists do not just resort to picking random answers concerning the phenomenons around us.

Since the question says observation and experiments were done it is scientific

- Surface area is the outer part of something.
- Mechanical weathering or physical weathering is highly renowned agent for increasing the surface area of rocks.
- When rocks fracture they creates cracks called joints.
- Joints increases the amount of surface exposed.
- Chemical weathering goes faster in surfaces with increased surface area.
