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. Brandon England is one of those people

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.

The Chemistry of Toothpaste Toothpaste is not a new thing. It has been traced back to Ancient Egypt. They used a powdered rock and vinegar‚ which created a chemical reaction that dissolves the plaque on teeth. In 1900’s people used hydrogen peroxide and baking soda or chalk‚ pulverised brisk and salt as a toothpaste. Toothpastes today‚ are mostly made up of abrasives‚ surfactants‚ a detergent‚ a thickener‚ a moisturizer‚ water‚ flavouring agents‚ coloring‚ sweeteners‚ fluoride and desensitizers

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

Major Chemistry questions: 1. Analyse the progress in the development and use of a named bioploymer. This anslysis should name the specific enzyme(s) used or organism used to synthesise the material and an evaluation of the use or potential use of the polymer produced related to it’s properties.
