How are egg shells and the enamel of your teeth the same?
Both teeth and eggshells are made of stone-like minerals containing mostly calcium. Bird eggshells are made of calcium carbonate, whil dental enamel is formed from calcium phosphate. Both of these materials are classified as COMPOSITES because they are actually not pure calcium carbonate or phosphate, but also contain additional components that are softer, and allow the mineral-like crystals to bond together into a rigid structure. The precise way the composite is organized, at the microscopic level, determines whether the material is hard and resiliant (like enamel) which is resistant to cracking, or hard and brittle like eggshell that cracks much more easily. To read more about how nature uses different materials, see if you can obtain a copy of the book--- _Life's Devices_, by Steven Vogel, 1988, Princeton University press--- from a local library. Or ask one of the librarians to help you find more information on the subject if the book isn't readily available.

Why detergent does not produces lather with hard water?
the hardness of water is mainly due to the presence of Ca or Mg ions.when hard water containing these ions is treated with soap solution it reacts to form white curdy ppt. known as "scum". 2C17H35COONa + Ca+2 -------> (C17H35COO)2Ca + 2Na+ (soap soln) (scum) the hardness is divided into two: 1) permananent Hardness(because of the precense of salts of ca or mg ions) 2) Temporary Hardness(due to the precense of bicarbonates)
