Example's of Chemical & Physical Changes

Observation	Example of Chemical Change	Example of Physical Change
Bubbles are produced.	Mixing baking soda and vinegar	Water boiling
There is a colour change.	Mixing potassium with lead nitrate.	-
The starting material is used up.	Mixing copper sulfate with distilled water.	Solubility
Heat is produced or absorbed.	-	-
A solid (precipitate) forms.	-	-

k, guys, I need examples, can anyone help me? I can't think of any..

Awww, Vaish! Good luck on that 😳 I have no ideaa yaar.. Science confuzes me 😆 Sorryzz[/b[

Lol, it's okay, thanks anyways, I thought of a few more, only need three now.

im really sorry....ive got no talent for science inside my head 😆

Oh thatz good 😛

The 4th one down (Heat is produced or absorbed)...the chemical change would just be endothermic or exothermic right (endo - absorb heat; exo- release heat) and the example of chemical change would be too see if the reaction vessel heats up or not..

do not fear, Areej is here😃

k well for chemical a really common one is if you combine silver nitrate with sodium chloride

and for physical would freezing water into ice be good enough??😕

hope it helps😉
