Chemistry GCSE Revision: Energy Changes

All chemical reactions involve energy and energy changes in various forms, including heat, light, and sound. For example, exploding dynamite is simply a rapid chemical reaction that releases a large amount of energy in a matter of microseconds. When heated, dynamite pushes nearby objects and the surrounding air outwards, sending shockwaves and shrapnel. Energy changes in a chemical reaction can...

What Is Titanium Dioxide Used For?

Titanium dioxide has been used for more than a century in various industrial and household applications. Chemically, its IUPAC (International Union of Pure and Applied Chemistry) name is titanium(IV) oxide, but it’s also informally known as titania.  This is a naturally-occurring substance that has a relatively simple formula, TiO2. It’s most commonly used as a pigment, which you may recognise...

Chemistry GCSE Revision: Quantitative Chemistry

Quantitative chemistry can seem intimidating because of how maths-based it is. But it’s not as scary as it sounds, and being well-prepared will help! Revising quantitative chemistry for your chemistry GCSE will help you familiarise yourself with key concepts and reinforce your existing knowledge. It also allows you to digest the fundamental ideas of the subject, including stoichiometry and...

What Is Xylene Used For?

Xylene is used for various industrial purposes, such as in the manufacture of terephthalic acid and dimethyl terephthalate monomers, where it’s used as a chemical precursor. This is one of its most important uses because these are the monomers responsible for creating polymers for plastics, particularly polyethylene terephthalate (PET) and polyester fabrics. Xylene is also used as an industrial solvent...
