Chemical Reactions, Catalysts, And Gas Laws - 983 Words

What started out as an April Fools’ Joke of a topic turned into a serious chemistry examination all thanks to a video from Scientific American. This video and article discusses a group of beetles called Bombardier Beetles. This insect has a very interesting and has a unique defense mechanism that gives the group it’s common name. They spray a very hot toxic liquid to discourage predators. Interestingly, the bug doesn’t use muscular contractions to discharge the deterrent, it uses an explosion inside its body. (Augenbraun,2016). There are three concepts that can be addressed regarding this explosive reaction that we have covered in our class: chemical reactions, catalysts, and gas laws. Chemical reactions are where one or more substances are changed into another or multiple other substances based on the properties of the reactants. We learned about 4 types of reactions; Synthesis or where reactants A B combine and create product AB, Decomposition where subs tance AB is broken apart into substances A and B, Substitution reaction where reactants A and BC get rearranged into products AC and B, and finally the double replacement reaction where reactants AB and BC react and make products AD and BC. According to the Scientific American Article by Augenbraun, the beetle combines two compounds, hydroquinone and hydrogen peroxide which together are non-reactive. But then peroxidase enzymes are added, which acts as catalysts that not only makes it toxic but causes it toShow MoreRelatedFactors That Affect The Rate Of Reaction Of A Chemical Reaction1154 Words   |  5 Pagesrate of reaction in a chemical reaction. Catalysts achieve this by lowering the amount of energy required for a reaction to take place, which means that it occurs at a quicker rate. Potentially, molecules that would once have taken years to interact, can take seconds with the addition of a catalyst. The overall purpose of a catalyst is to ensure that reactions proceed effec tively which is why a range of catalysts are commonly used in many elements of society. Common examples of where catalysts are usedRead MoreThe Effect Of Concentration On The Rate Of Reaction1563 Words   |  7 Pageswill result will be a slower rate of reaction. Therefore, it is also hypothesised that the addition of a catalyst will cause the rate of those reactions to speed up, was proven correct by the results of this experiment, in that the changing of the concentration and the addition of a catalyst changed the speed at which the reaction occurred. The results from both Part 1 and Part 2 conclusively showing that the have a direct effect on the rate at which the reaction occurs. In order to come to this conclusionRead MoreChemical Reactions And Gas Laws1284 Words   |  6 Pagesshame and all around is frowned upon in public. Despite its harsh reputation, flatulence is normal, and everyone experiences it throughout his or her daily lives. Flatulence is directly related to th e world of chemistry, both involving chemical reactions and gas laws. In the end, while flatulence might be the cause of smelly situations, it also shows that chemistry is not limited to the laboratory, it is seen throughout the world, even in the human body. When people think of flatulence, they areRead MoreKinetics Lab793 Words   |  4 PagesHydrogen Peroxide Introduction: Chemical reactions are dependent upon two factors: temperature and concentrations of substance. We can monitor the rate at which a chemical decomposes or the rate at which a chemical substance appears. In this experiment we will be measuring the rate of decomposition of hydrogen dioxide with the following reaction: 2 H202 (aq) 4 2 H20 (l) + 02 (g) We can trap the oxygen gas created into a container thus showing the extent of the reaction and this will show the rateRead MoreA Study On Chemical Reactions1562 Words   |  7 Pages 006/7th Review of Literature A chemical reaction is the â€Å"communication† (or interaction) between elements (Green, 2012). Chemical reactions can happen naturally or can be caused by a person. They can even happen inside of a living being (Newmark, 2000). Some chemical reactions can just happen randomly and others need different amounts of energy for them to occur. Heat can provide chemicals with the energy for this to happen. For example, dynamite is extremelyRead MoreThe Six Branches Of Chemistry1482 Words   |  6 Pagesthe study of the structure, properties, and preparation of chemical compounds that consist primarily of carbon and hydrogen. organic chemistry the study of most carbon containing compounds INORGANIC CHEMISTRY Inorganic chemistry is the study of the properties and behaviour of inorganic compounds.

Also, the rate reaction can be express in an equation known as the rate law. The rate law can be express as rate=f([A],[B],[C],†¦) (1) where the rate reaction is represented as a function of the concentrations in the chemical equation with time.3 The general chemical reaction can be shownRead MoreCalculating Quantities And Classification Of Chemical Reactions1981 Words   |  8 PagesClassification of Chemical Reactions Lab Purpose: I. The objective of this laboratory experiment is to be able to identify and precisely classify each reaction as one of the five different types of chemical reactions by comparing the reactants from the product. II. The purpose of this laboratory experiment is to accurately calculate quantities of the products and the reactants, Aluminum and Copper (II) Chloride, in the chemical reaction to determine its percent yield.

Whereby these catalysts don’t take place in any reactions happening but only triggers them. The diagram shows how less harmful gases are produced to the atmosphere by the reduction catalyst and oxidation catalyst. The three way catalytic converter uses two stages to accomplish the process of reducing toxic emissions, the first stage takes place on the reduction catalyst. The second stage of the process happens on the oxidation catalyst. Platinum and rhodium are
