Question

drag each tile to the correct location. which type of change does the statement describe? particles rearrange into new combinations, forming new substances. there is no change in the chemical properties of the substance. particles retain their composition and identity. the chemical properties of the substance change. physical change chemical change

Explanation:

To solve this, we recall the definitions of physical and chemical changes:

• Physical Change: Involves a change in physical properties (like state, shape) without forming new substances. So, during physical change, the chemical properties of the substance remain unchanged (since no new substance is formed), and particles retain their composition and identity.
• Chemical Change: Involves the formation of new substances through a chemical reaction. So, particles rearrange into new combinations (forming new substances), and the chemical properties of the substance change (because a new substance with different properties is formed).

Answer:

• Physical Change:
• There is no change in the chemical properties of the substance.
• Particles retain their composition and identity.
• Chemical Change:
• Particles rearrange into new combinations, forming new substances.
• The chemical properties of the substance change.
