Identify the chemical change in thefollowing list....... A Chemical change is something that alters themolecular structre of something - for example iron can turn intorust -- but rust IS NOT IRON. This is a chemical change(rather than a physical one). ONe the other hand, if youbroke a piece of iron in half, it is stilliron.a. gold metal formed from goldchloride in solution This IS a chemical change - you are altering thestructure of gold and making it something completely new -- goldchloride!!
b. wwax is melted out of a mold in akiln Melting wax is a change of phase - it is a physicalchange. The wax is still wax, now it is just liquid insteadof metal.
c. plaster of paris is ground topowder for making a mold Just like in B, grinding something doesnt changewhat it is - it was plaster of paris, and after grinding it, itstill is
d. a gold ring is resized to fit anew owner This is also a physical change, the gold is beingstretched and bent, but it is stillgold!!
e. a diamond is set into agold ring In the beginning you had gold and you haddiamond - that is still what you have. Now, if you reactedthe gold with the diamond to make some super-jewlery, that would bea chemical chaneg.
