So you could say that you are made of different elements, right Aspirin?
Yes that is correct.
Well, I am made of glucose, carbon dioxide, proteins, mineral ions, hormones, red blood cells and white blood cells, platelets. However, all of these are not chemically combined.
Guys, do you know that we can go through chemical and physical changes as well?
Wow, calcium, tell us more.
Well, for example, as an element I can chemically or physically combine with phosphate to form the compound Hydroxyapatite which forms the mineral portion of the bones and teeth.
As I mentioned before, I am made of Carbon, Hydrogen and oxygen. These elements are chemically combined to make me. Hence, if you want to get oxygen from me, it won't be possible as chemically combined compounds cannot be separated again.
I am physically combined with glucose, carbon dioxide, proteins, mineral ions, hormones, red blood cells and white blood cells, platelets. Hence, if you want to get carbon dioxide from me, you can because physical change can be reversible.
