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?
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.
Based on the information provided, it appears to be a chemical change. This is because new substances are being formed, as indicated by the green liquid turning into a blue liquid.
Based on the given information, this type of change is a chemical change.
A chemical change refers to a process that results in the formation of new substances with different chemical properties. In this scenario, several observations point to a chemical change:
1. The clear liquid being poured into the test tube: This indicates that a new substance is being introduced into the system.
2. The coin letting out green and orange liquid as it bubbles: Bubbling is often a sign of a chemical reaction taking place. The green and orange liquids are likely the result of chemical reactions occurring between the clear liquid and the coin's materials.
3. The green liquid slowly turning into a blue liquid: This color change suggests the formation of a new substance, indicating a chemical reaction.
4. The orange liquid staying the same: Although there is no change in this liquid, the fact that other substances are undergoing a chemical reaction suggests that the overall process is chemical in nature.
To determine the type of change, it is important to consider the evidence of new substances being formed, color changes, bubbling, and the introduction of a clear liquid that initiates these reactions.
