1Invested a considerable amount of money in buying a technique that had a huge impact on the success of his well-known business. 2Invented a chemical formula that was successful only in a lab experimental stage yet marked the beginning of an important era. ...
A water molecule has a very simple chemical formula, H2O, two hydrogen atoms bonded to one oxygen atom. But water is pretty remarkable in terms of all the things it can do. Remember from the Earth’s Minerals chapter that water is a polar molecule. The positive side of the molecule attra...
The chemical formula and crystal lattice of a mineral can only be determined in a laboratory, but by examining a mineral and determining several of its physical properties, you can identify the mineral. First, you need to become familiar with the physical properties of minerals and how to recog...
B: While Western medicine is purely a science, Chinese medicine is more of a healing art. Chemical compounds are used to formulate medications in Western medicine, but only herbs are used for traditional Chinese treatments. Almost every plant is seen to have some health benefit to the body, ...

I have always felt that I understood a phenomenon only to the extent that I could visualise it. Much of the charm organic chemical research has for me derives from structural formulae. When reading chemical journals, I look for formulae first. ...
