Question

physical change: the physical properties change but the type of substance. what are some examples of physical changes? there is no change in the makeup of the substance(s) that are changed. physical changes can be more easily than chemical changes. physical change rearranges molecules or substances but does not affect their chemical structures. chemical change: properties change and a different is produced. chemical changes cannot be reversed. examples: iron reacts with and water to form iron oxide (rust) silver reacts with to form silver oxide (tarnish)

Explanation:

Physical change only affects physical properties like shape, state, etc., without altering the chemical composition. Examples include melting ice (solid - liquid change), cutting paper (shape change). Chemical change results in a new substance with different chemical properties and is generally not easily reversible. For example, iron reacting with oxygen and water to form iron oxide (rust) is a chemical change as a new compound is formed. Silver reacting with substances to form silver oxide (tarnish) is also a chemical change.

Answer:

What are some examples of physical changes? Melting ice, cutting paper.
The physical properties change but the type of substance: Remains the same in physical changes.
There is no change in the makeup of the substance(s) that are changed: In physical changes.
Physical changes can be: Reversed more easily than chemical changes.
Physical change rearranges molecules or substances but does not affect their chemical structures: True for physical changes.
Chemical Change: Results in a different substance being produced.
Properties change and a different: Substance is produced in chemical changes.
Chemical changes cannot: Be reversed easily.
Examples: Iron reacts with oxygen and water to form iron oxide (rust), silver reacts with substances to form silver oxide (tarnish).
