Chemistry : Physics Of Matter And Energy And The Interaction Between Them

1500 Words6 Pages
Chemistry is the study of matter and energy and the interaction between them. Chemistry sometimes referred to as the central science because it connects other sciences to each other, such as biology, astronomy, medicine, physics, geology and environmental science. Chemistry is everywhere in the world around us; It 's in the food we eat, water we drink, medicine we take, clothes we wear, air, even the body is made of chemicals. Chemical reactions occur when we breathe, eat, run, or lay down. We are all chemists as we use chemistry every day and perform chemical reactions without knowing it or thinking about it.
Chemistry has a reputation for being a complicated and boring science, but for the most part, that reputation is undeserved

The most common types of chemical reactions include:

Belousov-Zhabotinsky Reaction
The first reaction that will be discussed is the Belousov-Zhabotinsky Reaction. This reaction was first observed by a Russian chemist called Boris P. Belousov and a graduate student by the name of student Anatol Zhabotinsky (Journal of Chemical Education, 2013).
This reaction is a type of oscillating reactions. What’s different about this reaction is it does not follow the normal pattern observed for most chemical reactions. Most chemical reactions observed proceed to completion or reaching some sort of equilibrium. Also, in most chemical reactions the concentrations of species involved depend primarily on the time. However, in oscillating reactions the reaction seems to not immediately reach equilibrium, but oscillate where the products of on reaction become the reactants of another reaction that interact to form the original reactants again. Also in oscillating reactions the concentrations of species can increase and decrease during the time of the reaction.
The mechanism for Belousov-Zhabotinsky Reaction is quite complex and is thought to involve about 18 different steps but two key processes occur; the first process generates molecular bromine, giving the red color, and the second process consumes the bromine to give bromide ions. The overall equation for this reaction is shown as:
3CH2(CO2H)2 + 4BrO3 → 4Br− + 9CO2 + 6H2O
