Chemical change.
What else can I help you with?
When a substance changes into a different substance a blank change has occurred?
If form changes but identity doesn't change then it is a physical change.
Are chemical changes when substances combine or are they when substances breaking apart?
A reaction between two substances or the decomposition of a substance are chemical changes.
When one substance changes identity it exhibits a?
When one substance changes identity, it exhibits a chemical change. This process involves the breaking and forming of bonds between atoms, resulting in the creation of new substances with different properties. Examples include reactions such as combustion, rusting, or fermentation, where the original substance is transformed into entirely different materials.
What kind of changes in substances are always physical changes?
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
How would you determine if a physical change had occurred?
To determine if a physical change has occurred, observe whether the substance retains its chemical composition. Key indicators include changes in state (such as melting or boiling), shape, or size without altering the substance's identity. No new substances are formed in a physical change, so if the original material can be recovered in its original form, it confirms a physical change. Additionally, physical changes are usually reversible, further distinguishing them from chemical changes.
