9.1 Orbitals and Theories of Chemical Bonding 1. Which one of the statements concerning valence bond (VB) and molecular orbital (MO) bond theories is correct? a) MO theory predicts that electrons are localized between pairs of atoms. b) In VB theory‚ bonding electrons are delocalized over the molecule. c) MO theory accurately describes bonding in O2 and NO‚ VB theory does not. d) VB theory can describe molecular bonding in excited states. e) MO theory is used to accurately predict

Inspiration: Life is like photography. You need the negatives to develop. Do you always think of what people say about you? Does it affect your daily basis and break down your motivation and inspiration? Always try to avoid negative people‚ they feed on your reaction and if they see you being affected by what they say or do‚ they’ll keep doing it. If paralympians had their minds posted to the bad comments people give‚ they would’ve never reached success. The reason why I chose the Paralympics

Allison Oneal Chemistry I June 20‚ 2013 Dr. Michael May Properties of Gases I. Abstract The purpose of this experiment is to examine the properties of several gasses‚ which were the products of a reaction‚ and examine the way the gasses react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Experiment Before I began the experiment I gathered all my supplies from the given list in the lab manual.

4.4.2 Viscosity Viscosity of a soup measured the internal friction of the soup or its tendency to resist flow (Chavan et al.‚ 2015). The result for viscosity of mushroom soups that analysed by viscometer (Brookfield model DV- Π + pro‚ America) was tabulated in Table 4.2. Viscosity of mushroom soup were significant different among different drying methods (p< 0.05). Fresh mushroom had lowest viscosity (750.50 ± 0.71 mpa.s) as compared the soup made from powders. Higher viscosity of mushroom soup

Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. With diffusion no energy is required and it is caused by kinetic energy. The rate of diffusion can be affected by many things including temperature‚ molecular weight‚ and movement. To test the rate of diffusion a drop of dark food coloring was added to a glass of tap water and it was timed to see how long it took for the drop to reach the bottom of the glass. This procedure was repeated three

Analysis of a Volatile Liquid Abstract: The purpose of this experiment was to use various methods of analysis to determine the identity of an unknown volatile liquid. In the first part of the experiment‚ the molecular mass was found by using water to find the volume of a flask through calculations and this as well as the mass of the gas of the unknown liquid were put into the a manipulated version of the ideal gas equation to determine the molar mass of the liquid‚ which was 14.21g per
