Question

A clear liquid is being poured inside the test tube and the coin lets out green and orange liquid as it keeps bubbling. The green liquid slowly turns into a blue liquid and the orange liquid stays the same.

what type of change is it? chemical or physical?

Answer 1

Based on the given information, it can be inferred that the change is chemical. This is because the clear liquid poured inside the test tube is likely causing a chemical reaction with the coin, resulting in the release of green and orange liquids and subsequent bubbling. Additionally, the transformation of the green liquid into a blue liquid suggests a chemical change taking place.
