Alternate Wordings for 'What is chemical change and physical change and give its examples?
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
When you mix a pink powdered substance in water and mix it is that a chemical change?
Mixing is not itself a chemical change. There could be one occurring as a result, but nothing you described indicated any kind of chemical change.
Examples af a chemical reaction?
