Substances which from very closely related crystals are said to be isomorphous, but it is not always very easy to decide when two substances are isomorphous. The term, moreover, is used somewhat loosely, for it originated from a consideration simply of the external form of crystals, and it was associated, by Mitscherlich’s law of isomorphism, with chemical composition. It is now realized that the requirement for isomorphism is similarity of internal structure, and, on this basis, isomorpho ...read more

Hydrogen peroxide is one of the hydrides formed by the combination of hydrogen with oxygen. The other hydride is water. Hydrogen peroxide was first prepared by Thenard by the action of dilute tetraoxosulphate(VI) acid on barium peroxide. He found out that H2O2 contained more oxygen molecule than water, H2O and this discovery prompted him to call it oxygenated water. This liquid  occurs in trace amounts in nature. It occurs in dews and in air. It also occurs in water that has been exposed to ...read more

Michelle Moscova, UNSW Hi I’m Miranda. I am ten years old and I live in California. My question is: why do older adults get shorter? What an interesting question, Miranda! Luckily, you don’t have to worry about this for some time. Until you are 30 or so (I know, it sounds old), you will continue to grow. However, after that, most people start to gradually shrink. So by the time you are 80 (yes, that seems really ancient), you would be 2-2.5 inches (5-6 centimetres) shorter. B ...read more
