Methane Molecule

Methane
 
Atoms exist all around us, whether it be in living things, or in inanimate objects. They are the basic building blocks of life. However, an atom comprises of a proton, neutron and electron. Protons are positively charged sub-atomic particles, electrons are negatively charged and neutrons have no charge. Atoms can also combine with compatible atoms, to form molecules. Molecules can either just comprise of an element, one type of atom, or a compound, multiple types of atoms. A common molecule found in the air is methane. Methane is an green house gas that is the seventh most prevalent gas in the ozone layer. Methane is used for heat and light, utilising its flammability. Methane comprises of Carbon and Hydrogen. But how do we actually identify methane in the air? Well there are two ways; the composition and structure, and the characteristics.

Hydrogen Peroxide

Hydrogen Peroxide

H2O2, otherwise known as hydrogen peroxide, is a transparent chemical compound that is commonly produced as a distilled liquid (Britannicacom, 2016). It is mostly used for bleaching various types of textiles and wood, manufacturing other chemicals, as rocket propellant, cosmetic use and medicinal purposes (Britannicacom, 2016). It can be found in rain, cleaning supplies, factories, mines and your local pharmacy (NZIC, n.d.) There are four steps in the manufacture of hydrogen peroxide. Those four steps are hydrogenation, filtration, oxidation and extraction (NZIC, n.d.)
