I suggest that this page be given a stub statis. . . Ryuugaki 23:28, 24 January 2007 (UTC)
I have posted a "stub" statis on this page. If you feel that this page deserves to be free of it, go ahead and take it off. However, it looked way too small to qualify as a full-length article. And to whoever wrote that comment down there, it helps if you leave some sort of a name. Ryuugaki 23:31, 24 January 2007 (UTC)
--- does Bubble bath go through a chemical change? Is this because the liquid bubble bath changes to bubbles that is a chemical change because of the water changing the liquid to foam?
What are some other examples of chemical change? please answer.(no name)
[edit] Dissolution of salt.
When NaCl dissolves in water, it dissociates into Na+ and Cl- ions. Clearly this is a chemical reaction.
Frankly, I think this chemical change/physical change discussion we have in grade 9 science is more confusing than helpful. You never hear physicists and chemists arguing over whether a change is physical or chemical. It has become a tradition to teach the concept, but I would love to dispense with it.
