The Electron Configuration of Atoms

Erwin Schrodinger designed the wave equation that utilized the two properties exhibited by an electron. These properties suggest that electrons exist both as a wave and a particle. Schrodinger’s work led to what is referred to as wave mechanics or quantum mechanics. In His work, Schrödinger treated an electron as...

Advantages and Disadvantages of Hydrogen Fuel

The hydrogen-powered vehicles utilize the hydrogen gas to power an electric motor. The hydrogen cars are electric vehicles (EV). The hydrogen gas only produces water and heat as byproducts. Hydrogen is the most basic element and among the most abundant and exist as compound rather than a single element. Hydrogen...

Classical Chemical Volcano

Classical chemical volcano refers to the eruption of ammonium dichromate [(NH4)2Cr2O7] in a classical chemistry illustration. The reaction is termed as one of the classics of chemistry demonstrations. During the presentation, ammonium dichromate glows and sparks due to decomposition. The decomposition of ammonium dichromate begins at 1800C but becomes self-sustaining...

Chemical Kinetics and Rate of Reaction

According to Houston 2013 (p. 106) in any chemical reaction, it is vital to note the extent to which the reaction takes place as well as its feasibility. Houston further states that whereas the feasibility of a reaction can be predicted using thermodynamics, the extent of a chemical reaction is...

Chemistry Contributions in the Discovery of Anticancer Drugs

Cancer is a cellular disease which arises from defects in the cellular mechanisms that control cell division thus resulting in the accumulation of large cell mass due to uncontrolled cell division. Cancer treatment is majorly based on chemotherapy, radiotherapy and surgery or a combination of either of the three. Most...

Determination of the Formula of the Iron (III) Thiocyanate Complex

To begin with, in every reaction involving chemical substances, the reaction does not always go under a completion reaction. Instead, such a system reacts to some intermediate level where the reverse reaction gets equal to the forward reaction. At this intermediate state, the concentration of products and reactants becomes constant...

Nomenclature of Alkenes

Organic Chemistry: Understanding Alkene Nomenclature and Reactions Organic chemistry has been an interesting topic so far. Understanding how organic compounds are named, different reactions and modifications to make new molecules are among the enlightening topics. However, it has been challenging to learn alkene nomenclature and some of the alkene reactions taught...

The Ionization Energy of the Periodic Table

Ionization Energy Ionization energy can be defined as the amount of energy that can be used to remove an electron from the outermost energy level of an atom in a gaseous state. IE usually depends on the number of valent electrons possessed by an element. We have the first IE which...

Chemical Weathering

Chemical Weathering Chemical weathering occurs when rainwater reacts with the grains of minerals in rocks to form soluble salts and clays. In particular, these reactions occur when the water is slightly acidic (Little and Lee 31). Chemical weathering especially oxidation, dissolution, and hydrolysis is the first step in the production of...

Determination of Heat Change in Chemical Reactions using Hess Law

Chemistry as a science that has several branches, one of them is thermochemistry. Thermochemistry is concerned with the study of heat changes during a chemical process, for example, in some experiment heat is absorbed or emitted during a chemical reaction.  The formula for change in enthalpy and Hess law can...

The Chemistry of Ketones and Aldehydes

Introduction Both aldehydes and Ketone contain the carbonyl group, and they are simple in structure because they lack reactive groups such as –Cl and –OH directly attached to the C atom in the carbonyl group. In a more advanced level, I would like to study the different products and the variety...
