behavior of gas molecules

All gases, irrespective of their chemical composition, obey certain laws that govern the relationship between the volume, temperature and pressure of the gases. A given mass of a gas, under definite conditions of temperature and pressure, occupies a definite volume. When any of the ..

Like all other first elements of the groups, oxygen also differs from its family members. The anomalous behavior of oxygen is due to its (i) small size (ii) high value of ionization energy and electronegativity (iii) absence of d-orbitals in the valence shell. Some of the important differ..

A molecule of water consists of two hydrogen atoms joined to an oxygen atom by covalent bonds...

>We are calling the total mass m t o t , because later on in the chapter, we use m for the mass of one molecule. Measurements of the behavior of various gases lead to several conclusions. First, the volume V is proportional to the number of moles n. If we double the number of mo..

Carbon atom has four electrons in its outermost shell. Thus, it requires four more electrons to acquire a stable noble gas configuration. Each of the hydrogen atoms has only one electron in its outermost shell and requires one more electron to complete its outermost shell (to acquire He..

An oxygen atom has six electrons in its valence shell. As a result, it requires 2 more electrons to achieve the nearest noble gas configuration. When two oxygen atoms share two pairs of electrons this is achieved: ..

Hydrogen atom has only one electron in its outermost shell, and requires one more electron to acquire the nearest noble gas configuration of helium (He:1s 2 ). To do so, two hydrogen atoms contribute one electron each to share one pair of electrons between them. This leads to the format..

A mole contains 6.023 x 10 23 particles. This is called Avogadro number. Molar volume is one mole of any gas at STP having a volume of 22.4 L. Mass of one mole of substance is called its molar mas..

It is a mixture of gaseous hydro-carbons. It is found usually along with petroleum deposits. Natural gas consists mainly of 85% methane, 10% of ethane and 3% of propane and butane. It may also contain nitrogen, oxygen, carbon di-oxide and hydrogen sulphide. Its great advantage is that it ..

Another simple equation of state is the one for an ideal gas. The figure below shows an experimental setup to study the behavior of a gas. The cylinder has a movable piston to vary the volume, heating can vary the temperature, and we can pump the desired amount o..
