identity?

Answer 2

A chemical change is a change in which a substance turns into a completely different substance that can't be reversed. A chemical change often happens when a substance burns (not to be confused with evaporation or melting of a substance), changes colors, a substance spoils or rusts, photosynthesis or respiration, and/or a substance tarnishes. Some examples are a bike rusting, burning bread to make toast, fireworks exploding, milk spoiling, a leaf changing color, mixing eggs and flour for a batter, baking a cake, etc. A chemical change will NOT dissolve, go through a state of matter (sublimation, decomposition, melting, freezing, evaporation, and condensation), breaking or tearing of a substance, and/or anything that can be reversed back.
