Although water is the most common hydrogen- oxygen compound, hydrogen and oxygen form another compound called hydrogen peroxide, H202. Hydrogen peroxide was first obtained by treating barium peroxide with an acid. Very small quantities of hydrogen peroxide are present in dew, rain, and snow because of the action of ultraviolet light on oxygen and water vapor. has different Hydrogen peroxide applications, depending upon its concentration. A 3 percent solution is used in the home as a mild antiseptic and germicide. A 30 percent solution is used in industry as a bleaching agent because of the permanency of the whiteness it produces. Concentrations of 90 percent are used as oxidizing agents in rockets and high explosives. many 30. According to the information in the passage, what can we predict that adding water to an industrial-strength hydrogen peroxide solution will result in? (blo A. an explosion B. a new substance C. an antiseptic D. rocket fuel E. a bleaching agent ebette JaoMceisie
Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.
