Introduction Alkanols (or alcohols) are a homologous series of organic compounds with the general formula CnH2n+1OH or simply ROH. Their molecules consist of a functional group — the hydroxyl group (—OH) joined to an alkyl group (R—). They can be used to fuel cars as they are flammable. Unlike alkanes, alkenes and alkynes, alkanols are

Did you know that drinking Coke out of a glass bottle tastes better than drinking from cans and plastic bottles? Science explains that it all has to do with how the fizzy drink reacts to the material it is being held in – and it seems to be better when surrounded by glass than a

Chemistry SS 2 Week 4 Topic: Chemical Equilibrium Introduction Chemical equilibrium has been reached in a reaction when the rate of the forward reaction is equal to the rate of the reverse reaction. When a chemical reaction has reached equilibrium, collisions are still occurring: the reaction is now happening in each direction at the same

Chemistry SS 1 Week 3 Topic: Mole Concept in Terms of Masses Numbers, Volumes of Reactants and Products Molar Mass The molar mass of any molecular compound is the mass in grams numerically equivalent to the sum of the atomic masses of the atoms in the molecular formula. The mole is just a number; it
Introduction Chemical equilibrium has been reached when the rate of the forward reaction is equal to the rate of the reverse reaction. When a chemical reaction has reached equilibrium, collisions are still occurring: the reaction is now happening in each direction at the same rate. This means that reactants are being formed at the same

ALLOY Introduction Many of the pure metals are not widely used because of their properties such as hardness, tensile strength, resistance to corrosion and lustre can be improved by combining them with other element. The mixtures are known as alloys. An alloy is a mixture of two or more metals mixed in a certain percentage.

Radioactive Decay Introduction Radioactive decay is the spontaneous radioactive disintegration of an atomic nucleus, resulting in the release of energy. Some atoms are stable. Others are unstable and ‘decay’, emitting radiation to achieve a stable state. The emissions from an unstable atom’s nucleus, as it decays, can be in the form of alpha, beta or
