Introduction To Chemical Kinetics

Chemistry deals with the conversion of substances into new substances through the formation and breakage of chemical bond. This conversion may happen at different speed. Some reaction happens instantaneously whereas some takes millions of years to happen. Reaction rates are of great importance. The feasibility of a chemical reaction particularly a commercial chemical process often depends on the reaction rate if the process is too slow it may not be suitable for commercial exploitation. It also relates, for example, what...

An Investigation Into Finding The Limiting Reagent In A Chemical Reaction

Introduction Stoichiometry is the section of chemistry that contains relationships between either reactants and/or products in a chemical reaction to assist in determining the required quantitative data (Nijmeh 2008, p1). Stoichiometry is used by chemists to give a detailed explanation on how much of certain materials are required in order to make a certain number of given products (Kailasa 2005, para.1). No products would be able to be made without chemical stoichiometry using balanced equations to calculate the number of...

The History Of Chemistry

Chemistry was first found in 1661 and its first modern chemist was called Robert Boyle. Boyle worked with gases and was the first to disagree with the Greek idea of four elements in his book The Skeptical Chymist published in 1661. This theory was odd because the Greek were the first people to record their studies and come up with the idea of elements as well as early models and atoms. Boyle also stated that “All reality and change can...

How Is Analytic Chemistry Used In The Medical Industry?

Introduction Analytical chemistry considers and employs a variety of equipment and methods in order to separate, identify and quantify matter. After the first flame tests in 1860, the importance of qualitative and quantitative analysis has been identified and major advancements have been made with many of the spectroscopic and spectrometric methods only being refined in the late 20th century. One of these methods includes the analytical technique ‘mass spectrometry’. Mass spectrometry assesses the mass-to-charge ratio of ions. Since mass spectrometry...

Chemistry Behind Fireworks

Have you ever wondered how fireworks actually work? Fireworks have been used for centuries as a source of entertainment, a method of communication and for religious reasons. Fireworks were invented in China. The earliest fireworks were made from hollow bamboo stalks filled with a simple chemical composition called ‘black powder’. This powder produces a small exploding reaction when ignited. In recent times, fireworks have evolved significantly in complexity in order to produce a great diversity of colours and patterns, and...

Chemistry In The Context Of Maths

I chose to study chemistry as part of a of a science degree with mathematics being my major area of study. Knowledge of basic maths is essential for understanding chemical processes and solving chemical problems. Stoichiometry is a great example of this as every step involves some level of maths, from balancing chemical equations to unit conversions. A strong parallel between chemistry and maths is the ability to use logic as part of the decision-making process when working through problems....

The Effect Of Concentration On Hydrochloric Acid On The Rate Of Reaction With Marble Chips

Rationale The main component of marble chips is calcium carbonate, CaCO3, which is an alkaline compound. With this property, marble chips are generally used as an acid neutralization material in many real-life applications, such as streams, lakes and soils where there is a certain level of acidity (Pol, 2020). When CaCO3 reacts with acid, for example hydrochloric acid (HCl), a salt (CaCl2), carbon dioxide (CO2) and water (H2O) are formed: CaCO3(solid) + 2HCl(aqueous)  CaCl2(aqueous) + H2O(liquid) + CO2(gas) (Equation...

Investigating The Effect Of Temperature On Chemical Reaction Rate

Rationale There are chemical reactions occurring all around us and without them, even humans would not be able to live. Chemical reactions have major factors that affect the rate of the reaction; temperature is one of those major factors. For example, bread dough rises more quickly in a warm place instead of a cool one, and warm-blooded animals regulate their body temperature so it is optimal for biomechanical reactions to run. A reaction only occurs when the molecules reacting have...

The Importance Of Chemistry In Scientific Disciplines

Chemistry is concerned with the complex arrangements and substances of which all of matter is made from. How these molecules react with other molecules and energy has given us our understanding of the universe as it is known. Therefore, I believe it is correct to view chemistry as a “central science”. Chemistry’s importance can be seen throughout most scientific disciplines. I have a particular interest in engineering, which chemistry finds itself intertwined with. Engineering would not be possible without a...

The Effects Of Hydrogen Ion Concentration On The Rate Of Enzymatic Browning Reaction Of Cut Apples

Introduction In our IB biology class, we’ve learned about enzymatic reaction and we’ve done the experiment on that unit. The experiment was about the rate of enzymatic reaction of lactosemilk by using an enzyme called lactase at different temperatures. At different temperatures, the rate of reaction changed. I was interested in this topic because there were more factors, not only temperature but also hydrogen ions concentration, presence of inhibitor, and concentration of substrate, which affect the rate of an enzymatic...

Use Of Computer And Augmented Reality In Chemistry Teaching

Chemistry had been regarded as a difficult subject for students by many researchers, teachers, and science educators because of the abstract nature of many chemical concepts, teaching styles applied in the class, lack of teaching aids, and difficult symbolic language of chemistry. For a better understanding of its concepts, students need to visualize chemical structures and molecules in three dimensions. Picturing chemical structures in three dimensions has consistently been troublesome. Traditionally, we have utilized molecular models for this reason, normally...
