Sulphuric Acid

Submitted by Utti on Thu, 28/07/2016 - 20:25

 

 
Sulphuric acid is a pungent-ethereal, colourless to slightly yellow viscous liquid that is soluble in water at all concentrations. It is highly corrosive, dense and oily and one of the most important of all chemical, prepared industrially by the reaction of water (H2O) with sulphur trioxide (SO3). In different concentrations, the acid is used to manufacture fertilisers, pigments, dyes and detergents as well as in petroleum refining and metallurgical processes. Its most common use is in lead-acid storage batteries. In this blog, there will be a detailed analysis of the use of sulphuric acid, its bonds and characteristics.

At the VRMath-2 3D Modelling Workshop at QUT, I created an ammonia molecule. The following blog will explain what ammonia is used for, as well as explaining the structure and uses of the individual atoms that make up the molecule.

Ammonia (NH3) is a molecule which consists of three hydrogen atoms and a nitrogen atom bonded together. It is a colourless, odorous, alkaline gas which is produced when organic materials decompose. This molecule is essential to many plants and animals, as a source of nitrogen. Additionally, bacteria within the intestines can produce the substance. Ammonia has many uses, though it is mostly used in fertilisers and cleaning products.

    The Potassium Atom

    Submitted by Rangerence on Thu, 28/07/2016 - 13:00

    Potassium is a chemical element classified the atomic symbol 'K' on the Periodic Table. As the seventh most abundant element on Earth (2.6% abundance in Earth's crust), potassium is found in a wide array of industries, despite being commonly known for its integral role as a mineral that allows human cell function and its presence in bananas. Some applications of potassium are (but not limited to) potassium-based fertilisers, pharmaceuticals and manufacturing. Discovered in 1807 by Sir Humphrey Davy, its abundance and simple atomic structure has allowed for exhaustive research and application regarding potassium.

    Chemistry and the idea of matter was first suggested by John Dalton in 1805 in his 'Atomic Theory' and over the century has been expanded on by many other scientists. Chemistry is the scientific category about substances of matter and their properties, compositions and the different reactions that take place when mixed together. Matter has a defined mass, takes up space and is composed of a mixture of elements. An element contains a group of only one type of atom. To identify elements refer to the periodic table which shows all elements with similar atomic structure and there atomic numbers. Atoms are the smallest parts that matter and elements can be divided into and are commonly known as the 'building blocks' of life.

    There are millions of things that exist on Earth, all of which are formed by atoms which are basic building blocks of matter.Every atom contains its unique atomic composition as well as chemical and physical properties. They combine to form molecules and crystal lattices in the form of an element or compound. The different combination of microscopic atoms create different substances.
