Which Events Involves A Chemical Change?

Which events involves a chemical change?

 

There are many scenarios that chemical change takes place. Below are only some:

Burning of any material, rusting, digestion and metabolism of the food we take, mixing an acid and a base, etc.

You can tell if its having a chemical and not a physical change usually when theres change in color, temperature change, forming of gas and odor, and if the result cannot be placed back into its original form.

I hope this helps! owo
