Chemical substance In organic chemistry, there can be more than one chemical compound with the same composition and molecular weight. Generally, these are called isomers. Isomers usually have substantially different chemical properties, and often may be isolated without spontaneously interconverting. A common example is glucose vs. fructose. The former is an aldehyde, the latter is a ketone. Their interconversion requires either enzymatic or acid-base catalysis. However, tautomers are an exception: the isomerization occurs spontaneously in ordinary conditions, such that a pure substance cannot be isolated into its tautomers, even if these can be identified spectroscopically or even isolated in special conditions. A
Blossom, Bubbles and Buttercup mysterious substance called "Chemical X" into the mixture, creating, instead of the "perfect little girl", three girls (each possessing one of the above elements dominating her personality), and granting all three superpowers including flight, superhuman strength, super speed, near invulnerability, x-ray vision, super senses, heat vision, energy projection, invisibility, and control over lightning. In the original pilot, the accidental substance was a can of "Whoopass", which was replaced by "Chemical X" in the aired version. The three girls all have oval-shaped heads, abnormally large eyes (inspired by Margaret Keane's art), stubby arms and legs, and lack noses, ears, fingers, necks,
