It is also a key component of Black Damp, caused by biological oxidation such as rotting mine timbers.

It is a member of the chalcogen group in the periodic table , a highly reactive nonmetal , and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. After hydrogen and helium , oxygen is the third- most abundant element in the universe by mass. At standard temperature and pressure , two atoms of the element bind to form dioxygen , a colorless and odorless diatomic gas with the formula O 2.

Allotropes Some elements exist in several different structural forms, called allotropes. Each allotrope has different physical properties. For more information on the Visual Elements image see the Uses and properties section below. Group A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell.

Use caution: Liquids with this reactive group classification have been known to react with the absorbents listed below.

Flammability 0 Will not burn under typical fire conditions. Instability 0 Normally stable, even under fire conditions.

Joseph Priestley and the Discovery of Oxygen

Matter is all around us. The desks we sit at, the air we breathe and the water we drink are all examples of matter. But matter doesn't always stay the same. It can change in many different ways. In this chapter, we are going to take a closer look at physical and chemical changes that occur in matter. A physical change is one where the particles of the substances that are involved in the change are not broken up in any way.

Where is this substance collected? 4) Two notable physical properties of oxygen are its low solubility in water and a density greater than air. a. Which one of.

Oxygen is a highly reactive nonmetallic element; it is a strong oxidizing agent with high electronegativity and forms O 2 at Standard Temperature and Pressure STP. Oxygen is an important part of the atmosphere and is necessary to sustain terrestrial life. Because it comprises most of the mass in water, it also comprises most of the mass of living organisms. All major classes of structural molecules in living organisms, such as proteins, carbohydrates, and fats, contain oxygen, as do the major inorganic compounds that comprise animal shells, teeth, and bone.

Oxygen O , nonmetallic chemical element of Group 16 VIa, or the oxygen group of the periodic table. Oxygen is a colourless, odourless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere. Oxygen forms compounds by reaction with practically any other element, as well as by reactions that displace elements from their combinations with each other; in many cases, these processes are accompanied by the evolution of heat and light and in such cases are called combustions.

4: The Properties of Oxygen Gas (Experiment)

Oxygen is one of the most abundant elements on this planet. Oxygen exhibits many unique physical and chemical properties. For example, oxygen is a colorless and odorless gas, with a density greater than that of air, and a very low solubility in water. In fact, the latter two properties greatly facilitate the collection of oxygen in this lab. Among the unique chemical properties of oxygen are its ability to support respiration in plants and animals, and its ability to support combustion. In this lab, oxygen will be generated as a product of the decomposition of hydrogen peroxide. A catalyst is used to speed up the rate of the decomposition reaction, which would otherwise be too slow to use as a source of oxygen.

За несколько лет работы ТРАНСТЕКСТА ничего подобного не случалось. Перегрелся, подумал. Интересно, почему Стратмор его до сих пор не отключил.

 Вот и прекрасно. Мистер Густафсон остановился. Наверное, он сейчас у. - Понимаю.  - В голосе звонившего по-прежнему чувствовалась нерешительность.  - Ну, тогда… надеюсь, хлопот не .

Она молила Бога, чтобы Стратмору звонил Дэвид. Скажи мне скорей, что с ним все в порядке, - думала.  - Скажи, что он нашел кольцо. Но коммандер поймал ее взгляд и нахмурился. Значит, это не Дэвид. Сьюзан почувствовала, что у нее перехватило дыхание. Она лишь хотела знать, что человек, которого она любит, в безопасности.

 Это лето было такое ужасное, - говорила она, чуть не плача.  - Я вам так признательна. Я так хочу выбраться отсюда. Беккер легонько обнял. Девушка высвободилась из его рук, и тут он снова увидел ее локоть.

Затем они приобретали как бы полупрозрачность, завершаясь у пола непроницаемой чернотой - посверкивающей черной глазурью кафеля, отливавшей жутковатым сиянием, создававшим какое-то тревожное ощущение прозрачности пола. Черный лед. В центре помещения из пола торчала, подобно носу исполинской торпеды, верхняя часть машины, ради которой было возведено все здание.
