1 Molecular-Orbital Theory Introduction Orbitals in molecules are not necessarily localized on atoms or between atoms as suggested in the valence bond theory. Molecular orbitals can also be formed the LCAO where more than two atomic orbitals are used. (Technically‚ we can use all of the atomic orbitals in the LCAO.) Linear combinations of orbitals result in the interference of waves. Both constructive and destructive interference may result. Within a diatomic molecule‚ N atomic orbitals

<i>1. State the five assumptions of the Kinetic-Molecular Theory of gases.</i><br><br>a) Gases consist of large numbers of tiny particles. These particles‚ usually molecules or atoms‚ typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids.<br><br>Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared

Ultra thin film coatings can be used in a wide range of applications as lubricants‚ anti-stiction layers‚ molecular glues‚ coupling agents or adhesion layers. The mentioned molecular coatings are used to modify material surface properties. The traditional coating deposition methods consist of a set of sequential wet baths. The wet processing method is complex and limits the ability of molecular coating in many MEMS applications. The use of liquid precursors has extremely limited bath life‚ which cause

1. Atomic and Molecular Structure a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. The Periodic Table organizes elements by their atomic number - from hydrogen (1) to whatever is the highest one currently known (>105). It is arranged so that similiar members fall in a list such as Chlorine Bromine etc.. The average atomic weight is usually shown with each element‚ but due to isotopes (caused buy nuclear varations)

I. Purpose The purpose of this lab is to determine the molecular mass of a volatile liquid. II. Procedure • Place a cork with a small hole in it inside of a test tube and find the weight of the two together using a sensitive balance. • Pour 0.5 mL of the unknown volatile liquid into the test tube‚ insert the cork‚ and place the tube into boiling hot water while keeping the cork above water level. As the gas evaporates‚ excess gas will be released throughout the whole in the cork. Keep the test

Empirical and Molecular Formula | Key Concepts * Empirical Formula of a compound shows the ratio of elements present in a compound. * Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound. * The empirical formula mass of a compound refers to the sum of the atomic masses of the elements present in the empirical formula. * The Molecular Mass (formula mass‚ formula weight or molecular weight) of a compound is a multiple of the empirical

Introduction In these few years‚ molecular gastronomy has become a key topic and it is the new fashion for chefs to offer their customers. This is a new culinary trend called molecular cooking has been investigated as the most exciting development in haute gastronomy. Molecular gastronomy is refers to a modern style of cooking‚ which is a discipline practiced by both scientists and food professionals that studies the physical and chemical processes that occur while cooking. As well as it is the
