What is Chemistry? Chemistry is the study of matter and energy and the interactions between them. This is also the definition for physics‚ by the way. Chemistry and physics are specializations of physical science. Chemistry tends to focus on the properties of substances and the interactions between different types of matter‚ particularly reactions that involve electrons. Physics tends to focus more on the nuclear part of the atom‚ as well as the subatomic realm. Really‚ they are two sides of the

Determination of Trace Amount of Copper and Zinc in an Aqueous Solution by Atomic Absorbance Spectroscopy Abstract: The purpose of this experiment is to analyze a sample containing copper and zinc in trace amounts‚ where standard addition method was used and the instrument used is the atomic absorbance spectroscopy. The amount of copper obtained was 0.569 ppm ± 0.015 and for zinc we obtained 0.42 ppm ± 0.0027. Introduction: This method implies the excitation of particles in the solution sample

SOUL Highly energetic chemistry is believed to have produced a self-replicating molecule around 4 billion years ago and half a billion years later the last common ancestor of all life existed. The current scientific consensus is that the complex biochemistry that makes up life came from simpler chemical reactions. The beginning of life may have included self-replicating molecules such as RNA‚ and the assembly of simple cells.1‚ 2 Fig-1: DNA Double Helix Heritable traits are known to be passed from

The brain and the spinal cord of the central nervous system are buffered by a number of protective layers known as the meninges. These include three main membranes of connective tissue including: the dura mater‚ the arachnoid layer and the pia mater [6]. The two innermost layers‚ collectively known as the leptomeninges‚ include the pia mater and the arachnoid mater that buffer the brain and spinal cord [7]. As indicated in image III below‚ the subarachnoid space is the area located between the

Eating Disorder April R. Gaines Alcorn State University Eating Disorder An eating disorder is when a person experiences severe changes in eating behavior‚ such as a very low dose of food intake or a high dose of overeating‚ or worry about body weight or shape. A person with an eating disorder begins eating smaller or larger amounts of food than usual and then the situation gets out of control. Eating disorders are very complicated; the biological‚ behavioral and social
