* Introduction to Organic Chemistry Understand the basis of drawing organic structures Depicting 3-D structures in 2-D Most organic compounds have a three-dimensional structure. How do we represent structures on our two-dimensional page? For example‚ methane is a tetrahedral molecule: Bonds in the plane of the paper: Bonds coming towards the observer: (out of the page) Bonds going away

Heading for 2050: The future in a nutshell Introduction This report is mainly surrounding the idea of technology evolution in 2050 in comparation to the present and with our current trends. It will merely present how the life can become even easier and simplified‚ the inaccesibility to information is almost nullified and how the nowadays Sci-fi ideas can become reality. 1. Accesibility First of all‚ when you think about the present‚ you think at how much the technology has evolved compared

Making Connections: Chemistry Assignment By. Sujay Sukumar 5. a) When analyzing the graph‚ a relationship between the hydrocarbon chain of the alkane and its corresponding boiling point can certainly be noticed. There is a increasing correlation which can be explained using the theory that as each hydrocarbon chain gets bigger‚ there are more atoms and thus more electrons which contributes to higher dispersion forces and therefore a higher boiling point which is clearly seen through the graph.

A Comparative Study On The Combustibility Of Ethanol (C2H5OH) And Hydrogen Peroxide (H2O2) Mixtures As Fuel Chemistry January 31‚ 2013 Revised February 15‚ 2013 Abstract In this experiment‚ the proponents used mixtures with varied proportions of ethanol and hydrogen peroxide to know which would make a more efficient‚ clean‚ and stable combination. Compared to conventional fuels‚ ethanol contains 36% oxygen thus resulting in more complete combustion. This greatly lowers

The Chemistry of Lipids Experiment #8 Objective To observe the solubility of lipids in polar and nonpolar solvents and to compare saturated and unsaturated fats in their chemical reaction with bromine. The percent fat in a food will be determined by extraction of the fat and weighing it. Introduction Lipids‚ by definition‚ are natural substances that do not mix with water but dissolve in organic solvents. There are several classes of lipids‚ including: fatty acids‚ waxes‚ triacylglycerols

Unlike the brain where a person can continue to be “alive” without any electrical activity‚ without a heartbeat‚ a person cannot live. The average person doesn’t ever think about how or why their hearts lub dub every minute of every day until they die. For someone whose heart doesn’t beat properly‚ the lub dub is a frequent worry.
