Did you ever wonder what lit up those 'OPEN' signs when you passed the billions of restaurants and stores? The answer can be summed up using one word. Neon.

3D model of a silicon atom

My partner and I have decided to research and create a 3D model of the element silicon. Silicon is an element present in the periodic table, possessing the atomic number of 14. Its atomic mass number is 28.085 and its state at room temperature is solid. It is known to be the "seventh most abundant element in the universe and the second most abundant element in the Earth's crust" (Gagnon, S., n.d.). Silicon has various uses including improving the strength of aluminium alloys, helping the operation of electronic products in the form of chips and being the main material that solar panels are made of (SIMCOA, n.d.). Most silicon on earth is found in the crust as sand, quartz and rock crystals among others. The discovery of silicon is credited to Swedish chemist Jöns Jacob Berzelius in 1824. He heated chips of potassium in a silica container then washed away the byproducts.

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.

Hydrochloric Acid planetary model with protons and neutrons

Everything contains atoms. Atoms are the basic units of matter and the defining structure of elements. Atoms are made up of three differently charged particles: positively charged protons, neutral neutrons and negatively charged electrons. Protons and neutrons are heavier than electrons and reside in the centre of the atom, called the nucleus.

Ethane

Ethane, otherwise known as C2H6, is an organic compound which is a colourless, liquefied gas. It provides many uses including those from the industrial and a consumer point of view. Ethane is used in fuel, fuel additives, ion exchange systems, paint additives, pigments, plasticizers, building/construction materials, fabric products, textile products, leather products, food packaging and much more.

Water molecule

Imagine you are sitting with your feet in a pool (filled with liquid water), watching the steam (gaseous water) rise from the spa nearby as you sip a drink from your glass filled with ice cubes (solidified water). Not many other chemical substances can exist in all three states of matter within the same temperature range. In fact, water it is the only substance which naturally occurs in all types. This is why H2O (commonly called water) is one of the most interesting chemical compounds in the universe, as well as being essential for life! (We have never found any organism that doesn't contain H2O)  Apart from being the most abundant compound on the Earth's surface, it has many other unique properties such as it's polar covalent bonds.

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.
