Which observation most likely indicates that only a chemical change has taken place

Chemistry

salantis [7]2 years ago
4 0

The correct answer as to which observation most likely indicates that only a chemical change has taken place would that the change cannot be reversed.

When it comes to changes in a system, it can either be:

  • physical change
  • chemical change

When a substance undergoes a physical change, the original version of the substance can be recovered. In other words, physical changes can be reversible.

When a substance undergoes a chemical change, the original version cannot be recovered because an entirely new product would have been formed. In other words, chemical changes are irreversible.

Thus, once a change becomes irreversible, such a change is said to be a chemical change.
