Phosphate ion PO Pattern 1: For instance, if you know nitrate is NO3-,then nitrite is NO
Animals breathe in oxygen and breathe out carbon dioxide. One important use of oxygen is in medicine. People who have trouble breathing are given extra doses of oxygen. In many cases, this "extra oxygen" keeps people alive after they would otherwise have died.
But oxygen has many commercial uses also. The most important use is in the manufacture of metals. More than half of the oxygen produced in the United States is used for this purpose.
Naming Compounds – Part 2 – YouTube: This video explains how to use a chemical name to write the formula for that compound. Naming Acids and Bases Acid names are based on the anion they form when dissolved in water; base names follow the rules for ionic, organic, or molecular compounds. Chemistry Formulas Practice Lite App - Stimulates students’ mastery of the fundamental skill of naming compounds and writing formulas. The practice categories include ionic and molecular compounds, acids, bases, polyatomic ions, hydrocarbons, and organic functional groups. Aspirin (2nd edition) Compiled by David Lewis Edited by Colin Osborne and Maria Pack Designed by Imogen Bertin and Sara Roberts First published by the Royal Society of Chemistry in
Oxygen usually ranks third in the list of chemicals produced in the United States each year. Inabout billion cubic feet of oxygen was manufactured in the United States.
The gas is prepared almost entirely from liquid air.
Discovery and naming What is air? Ancient peoples thought deeply about that question. And that should not be surprising. It is easy to see how essential air is to many processes. Objects cannot burn without air.
Human life cannot survive without air. In fact, ancient peoples thought air must be an "element. To ancient people, an element was something that was very important and basic.
Air fit that description, along with fire, water, and earth. They often thought of air as an element in the modern sense—that it was as simple a material as could be found.
Yet, some early scholars believed otherwise. For example, some Chinese scholars, as early as the eighth century A. They called these parts the yin and yang of air.
The properties of the Chinese yin and yang can be compared to the properties of oxygen and nitrogen. The first person in Western Europe to describe the "parts" of air was Italian artist and scientist Leonardo da Vinci Leonardo pointed out that air is not entirely used up when something is burned in it.
He said that air must consist, therefore, of two parts: For many years, Leonardo's ideas were not very popular among scholars. One problem was that early chemists did not have very good equipment. It was difficult for them to collect samples of air and then to study it.
In the early s, chemists began to find out more about air, but in a somewhat roundabout way. For example, in andScheele studied the effect of heat on a number of different compounds.
When he heated these compounds, he found that a gas was produced. He then studied the properties of that gas. He found that flames burned brightly in the gas. He also found that animals could live when placed in the gas. Without knowing it, Scheele had discovered oxygen.General rule.
From Wikipedia:Naming conventions.
Generally, article naming should give priority to what the majority of English speakers would most easily recognize, with a reasonable minimum of ambiguity, while at the same time making linking to those articles easy and second nature.
