Potassium Hydroxide

By Patrick Schachtner
Atoms are the building blocks of everything. Atoms can be divided into 118 different elements. Potassium Hydroxide (KOH) is a combination of the elements of potassium, hydrogen and oxygen. Potassium Hydroxide, more commonly known as caustic potash, is a corrosive oxidiser which is found when sodium hydroxide (NaOH) reacts with potassium. It is mainly used as a fertiliser because of its water retaining properties. Potassium hydroxide is a common substance with many sources found around the world.

Ethanol Molecule


Atoms are the building blocks of all matter in the universe. They make up every object, material and substance. Atoms are made from protons, neutrons and electrons, and in different arrangements and quantities, form different atoms. 2 or more of these atoms can be grouped together to form molecules. Molecules are the smallest particles in chemical elements. An example of a compound is ethanol. This blog is written to show the molecule I have constructed, which is ethanol, and to explain its structure and characteristics. Also, I will share my experience creating the molecule, and what difficulties and questions I had about the creation process on VRmath2.0.

Quartz Molecule

Quartz molecule

All matter in the world is compounded from basic units of measurements called atoms. Atoms are made up of protons and neutrons, making the nucleus in the centre and electrons, which are much lighter in rings around it. Elements are substances made from only one type of atom, although when different atoms combine, they form compounds, or molecules. In a compound the atoms are being held together with chemical bonds. In this blog, I will be talking about the structure and characteristics of the molecule quartz.

Aluminium is the 13th element of the periodic table and has the atomic symbol of Al. It was first discovered in 1825 in Denmark by Christian Oersted (Winter, 2016). Aluminium is the most abundant metal in the earth's crust; however it is never found free in nature (Pappas, 2014). All aluminium that is used on earth comes from compounds as aluminium combines with other elements. Aluminium is very useful and can be seen from our everyday lives to large industrial uses. For example aluminium can be used in the form of foil to keep your sandwich fresh to building airplanes and jet engines. It is widely used due to the fact that it is plentiful, relatively inexpensive, strong yet lightweight, can combine with other materials easily, is resistant to heat and corrosion and a good conductor of electricity (Woodford, 2016).

Nitrous Acid Molecule

A molecule is when two or more atoms join chemically; nitrous acid is one of many molecules. Nitrous acid, which its chemical formula is HNO2, is an unstable acid and only exists in solutions or nitrite salt. Interestingly, it is naturally produced by the Earth's atmosphere, and when it reacts with water (H2O) and nitric oxide (NO), it helps regulate ozone layer in the atmosphere, which is currently being damaged by human activities. If this acid comes in contact with human, it may affect respiratory health and cause irritation, as it is slightly toxic. In this blog, it will present: 3D model of the acid composition; structure and characteristics; further information and questions; intriguing ideas and difficulties found in programming; and links to the 3D model and logo program.
