Source and Chemical Composition Origin from Latex: Natural rubber, or getah asli, is sourced from latex, a milky fluid extracted from rubber trees, primarily Hevea brasiliensis. Origin from Latex: Natural rubber, which is also called getah asli in Malay, is obtained from a white, milky liquid called latex. This latex comes from rubber trees, mainly … Read more
Definition and Production Man-Made Polymers: Synthetic rubbers (getah sintetik) are artificial polymers engineered to mimic the properties of natural rubber. Man-Made Polymers: Synthetic rubbers, also called getah sintetik in Malay, are special materials created by scientists in laboratories. These materials are not found in nature but are designed to copy or imitate the useful qualities … Read more
Basic Structure Esters Formation: Oils and fats are esters formed by the reaction of fatty acids with glycerol. Esters Formation: Oils and fats belong to a group of compounds called esters. These esters are created through a special chemical reaction where molecules called fatty acids combine with another molecule called glycerol. This combination creates a … Read more
Exothermic Reactions Definition: Exothermic reactions release heat to the surroundings, increasing the surrounding temperature. Definition: Exothermic reactions are chemical changes that give off heat to the area around them. Because of this, things near the reaction get warmer, and the temperature around the reaction goes up. It feels hot when you touch something involved in … Read more
Definition and Formation Definition of Polymers: Polymers are macromolecules made by repeatedly linking many small molecules called monomers. Definition of Polymers: Polymers are very large molecules, also called macromolecules, that are made when lots of smaller molecules, called monomers, join together in a chain. This process of joining makes the polymer strong and useful for … Read more
Introduction to Thermochemistry Definition: Thermochemistry is the branch of chemistry that studies heat changes during chemical reactions. Definition: Thermochemistry is a special part of chemistry that focuses on studying the heat (a form of energy) that is given out or taken in during chemical reactions. This helps us understand how much energy is involved when … Read more
Heat of Reaction Definition: Heat of reaction is the heat energy absorbed or released during a chemical reaction. Definition: The heat of reaction is the amount of heat energy that is either taken in (absorbed) or given out (released) when a chemical reaction takes place. This tells us whether the reaction makes the surroundings hotter … Read more
Definition Series concept: A homologous series is a group of organic compounds with the same general formula and similar chemical behaviour. Series concept: A homologous series is like a family of organic compounds that are very similar to each other. They all follow a pattern called a “general formula,” which means their chemical makeup is … Read more
Alkanes Structure: Alkanes are saturated hydrocarbons with single covalent bonds and the formula CₙH₂ₙ₊₂. Structure: Alkanes are a group of hydrocarbons, which means they are made from only hydrogen and carbon atoms. They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. All the bonds between the carbon … Read more
Isomers Definition: Isomers are compounds with the same molecular formula but different structural formulas, resulting in different physical and chemical properties. Definition: Isomers are special kinds of chemical compounds that contain the same types and number of atoms, meaning they share the same molecular formula. However, what makes them different is the way those atoms … Read more
