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

Introduction to Corrosion Corrosion Overview Definition of corrosion: Corrosion is the natural process where metals degrade into more stable forms like oxides or sulfides. Definition of corrosion: Corrosion is a slow, natural process where metals, which are usually shiny and strong, are gradually worn down and changed into more stable forms such as metal oxides, … Read more

Organic Compounds Definition: Organic compounds are those that contain carbon as a central element. Definition: Organic compounds are special types of substances that always contain carbon as one of their main building blocks. These compounds are very important because carbon can form many different shapes and bonds, which makes it easy to create a huge … Read more

Chemical Cells Overview Definition of chemical cells: Devices that convert chemical energy into electrical energy using spontaneous redox reactions. Definition of chemical cells: Chemical cells are special types of devices that can take the chemical energy stored inside substances and turn it into electrical energy that we can use to power things. They achieve this … Read more

Electrolytic Cells Overview Definition of electrolytic cells: Electrolytic cells use electrical energy to drive non-spontaneous chemical reactions. Definition of electrolytic cells: Electrolytic cells are special types of devices that take in electrical energy, like the kind from a battery, and use it to make chemical reactions happen. These chemical reactions would not happen on their … Read more

Introduction to Metal Extraction Metal Extraction Overview Occurrence of metals: Metals are usually found in nature as compounds within ores. Occurrence of metals: Metals are not usually found in their pure form in nature. Instead, they are combined with other elements to form compounds, and these compounds are found in rocks called ores. To get … Read more
