MOLECULAR MODELING 1. Objectives ● Predictthe shape of identified compounds; ● Construct molecular models of identified compounds; and ●Determine the molecular structure of identified compounds. 2. Theory Building models of molecules are useful for visualizing how atoms are connected in three-dimensional space called molecular geometry‚ which is best predicted by Valence-Shell Electron-Pair Repulsion (VSPER) theory. The following are the sets of rules summarizing thsi theory: ●

Planets of our Solar System The Earth: The earth is the fifth largest planet of the solar system. The life is possible on the earth because its gravity is sufficient to hold atmosphere and best conditions for sustaining life. It contains a large amount of water in the form of oceans. 71% parts of the total area is covered with water and the remaining 29% is covered with land. The temperature of the centre of the earth is 2000° C. The circumference of the earth is 40‚000 km. The earth completes

SPH4U-B 4 Circular Motion Physics SPH4U-B Lesson 4 Introduction Transportation has undoubtedly advanced. Not only have vehicles changed‚ but the means by which people can get themselves to and from different locations has changed as well. Maps and compasses now take a backseat to the Global Positioning System (GPS). Access to the GPS is now very widespread; 24 satellites above our atmosphere are used to send and receive information in order to accurately determine locations of

Module 1 Physics: The Basic Science What this module is about The study of science has two branches namely‚ the life sciences and the physical sciences. The life sciences include biology‚ zoology and botany. The physical sciences branch into areas such as geology‚ astronomy‚ chemistry and physics. However‚ physics is more than part of physical sciences because it does not only deal with matter and energy but it also deals with the other basic concepts like motion‚ forces‚ heat‚ sound‚ light

Jovian Planets Ranging between 4.95 and 30.4 AU away from the Sun are the Jovian planets. Jovian means of or relating to either the planet or the mythological god‚ Jupiter. The Jovian planets‚ also referred to as gas giants‚ are Jupiter‚ Saturn‚ Uranus‚ and Neptune. These planets all fit the category of being a Jovian planet due to the mutual inclusiveness of a thick atmosphere composed of hydrogen and helium. These planets are not solid‚ they only become denser further towards the core

Physics (from Greek)‚ i.e. "knowledge‚ science of nature"‚ from φύσις‚ physis‚ i.e. "nature"[1][2][3][4][5]) is a part of natural philosophy and a natural science that involves the study of matter[6] and its motion through space and time‚ along with related concepts such as energy and force.[7] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[8][9][10] Physics is the field of science that studies the physical world. From the large (galaxies

Mathematical modeling is commonly used to predict the behavior of phenomena in the environment. Basically‚ it involves analyzing a set of points from given data by plotting them‚ finding a line of "best fit" through these points‚ and then using the resulting graph to evaluate any given point. Models are useful in hypothesizing the future behavior of populations‚ investments‚ businesses‚ and many other things that are characterized by fluctuations. A mathematical model usually describes a

In this lab our goal was to see if we can prove if the acceleration due to gravity is 9.8m/s2. The R2 in this lab is closed to 9.8 m/s2 . The formula that we used in this lab is T=2πLg and then we solved for g=L(T2π)2. HYPOTHESIS: The gravity will be 9.81 m/s2 at sea level due to the acceleration. PROCEDURE: Materials: stopwatch‚ meter

It is also the largest of the Solar System’s four terrestrial planets. It is sometimes referred to as the world‚ the Blue Planet‚ or by its Latin name‚ Terra. Earth formed approximately 4.54 billion years ago‚ and life appeared on its surface within one billion years. Earth’s biosphere then
