Water scientific name

Using the same logic, the chemical compound H20 can also be named using the prefixes mono- and di-. Because there is only one oxygen atom in water and the oxygen is the second element in the compound, the prefix mono- is used. The scientific name for H20 is dihydrogen monoxide. Of course, this compound is also much better known by its common name—water.

Common names of some molecular compounds How frequently have you drunk an icy, cold glass of dihydrogen monoxide Quite frequently, hut you probably didn t call it that. You called it by its more common name, which is water. Remember from Chapter 8 that many ionic compounds have common names in addition to their scientific ones. Baking soda is sodium hydrogen carbonate and common table salt is sodium chloride. Many covalent compounds also have both common and scientific names.

Many binary molecular compounds, such as nitrous oxide and water, were discovered and given common names long before the present-day naming system was developed. Other binary covalent compounds that are generally known by their common names rather than their scientific names are ammonia (NH3), hydrazine (N4H4), and nitric oxide (NO). 

Blue crabs are known to all who frequent shallow waters along the east coast of North America. Their abundance and tasty meat have made them a major commercial fishery for hundreds of years. Lifestyles of people, even cultures, have been defined by them, as chronicled in William Warner s book, Beautiful Swimmers Watermen, Crabs and the Chesapeake Bay. In fact, the blue crab s scientific name, Callinectes sapidus, given in 1896 by Dr. Mary Jane Rathbun, at the time one of the foremost authorities on crustacean systematics, means good-tasting beautiful swimmer. That they are, but they are much more, as we hope we convey in this chapter. 

It is rarely that any greater degree of accuracy than that attained in the above methods is required. If, however, scientific accuracy is necessary in specific gravity determinations, the usual standard of comparison, at whatever temperature the determination may be made, is water at its maximum density temperature, namely 4°. If no correction is made for the weight of the air contained in the bottle or tube, accuracy to the fourth place of decimals is ensured by reducing the observed weighings to vacuum weighings. This can be done by the equation—... 

AB cements are not only formulated from relatively small ions with well defined hydration numbers. They may also be prepared from macromolecules which dissolve in water to give multiply charged species known as polyelectrolytes. Cements which fall into this category are the zinc polycarboxylates and the glass-ionomers, the polyelectrolytes being poly(acrylic acid) or acrylic add copolymers. The interaction of such polymers is a complicated topic, and one which is of wide importance to a number of scientific disciplines. Molyneux (1975) has highlighted the fact that these substances form the focal point of three complex and contentious territories of sdence , namely aqueous systems, ionic systems and polymeric systems. 

Think how many carcinogens are household names asbestos, cigarette smoke (a mixture of several thousand chemical compounds), DES, dioxin, saccharin, arsenic, PCBs, radon, EDB, Alar. Hundreds more of these substances, some very obscure, are known to the scientific and medical community, and many of these are scattered throughout the land at thousands of hazardous waste sites similar to Love Canal. People are exposed to these dreadful substances through the air they breathe, the water they drink and bathe in, and the foods they eat. Chemicals can also produce many other types of health damage, some very serious, such as birth defects and damage to our nervous and immune systems. 

There are two other temperature scales that still may be seen in old texts or journals, but are not acceptable for any current scientific work. Perhaps the rarer is the Reaumur scale (°Re). It separated the range between freezing and boiling of water into 80 units and was used in parts of Europe. The other temperature scale, the Rankine, may be referred to in old books on thermodynamics. It was named after W. J. M. Rankine, who did early research in that field. The Rankine is to Fahrenheit what Kelvin is to Celsius. In other words, just as one degree K = one degree C, one degree F = one degree R. Thus, 0 K = 0°R = -273.15°C = -459.67°F.
