Properties and Applications of Essential Metals
Magnesium
Minerals
Magnesium silicates
Process of Production
- Heat Treatment: Heat in an electric oven at a high temperature to obtain magnesium metal.
- Electrolysis: Cast magnesium chloride undergoes electrolysis to produce cast magnesium.
Properties
Bright white, very light, soft, malleable, slightly ductile, unalterable in dry air, corrodes in humid air, and reacts with O2 in powder form.
Applications
Pyrotechnics, reducing agent, refractory furnaces, agriculture, chemical industry, construction, and sports.
Read MoreUnderstanding Homogeneous Mixtures and Solutions
Homogeneous mixtures are uniform; that is, any portion has the same composition and properties. The blended components cannot be distinguished even with the aid of an electron microscope, which is the most powerful.
Homogeneous mixtures are also called solutions. Depending on the physical state of the mixture, solutions can be gaseous, liquid, or solid.
Gaseous Solutions
A set consisting of gases, such as the atmosphere, is made of 71% nitrogen, 21% oxygen, and 1% other gases.
Solid Solutions or Alloys

Sugar Production: From Cane Cultivation to Crystallization
**Sugar: From Field to Table**
Sugar, also known as sucrose (C12H22O11), is a disaccharide composed of glucose and fructose. It is commonly referred to as table sugar. Sucrose is primarily obtained from sugar cane or beets. In industrial settings, the term “sugar” or “sugars” may refer to various monosaccharides and disaccharides, which generally have a sweet taste. However, by extension, it refers to all carbohydrates.
Sugar can caramelize when heated above its decomposition point, resulting in a

Mixtures
Mixtures are formed by joining two or more substances in various proportions, each retaining its own characteristics. There are different types of mixtures based on how the components are combined. If the components of a mixture cannot be distinguished with the naked eye, it is homogeneous. If the components can be differentiated, it is said to be heterogeneous.
Benchmark Optical
This method is used to classify mixtures and is based on direct observation or indirectly through a magnifying

**Chemical Bonds: Types and Characteristics**
**Main Types of Bonds**
- Ionic or Electrovalent Bond (transfer of electrons)
- Covalent Bond (sharing a pair of electrons between two atoms)
- Coordinate Covalent Bond (one of the two atoms provides the pair of electrons to share)
**Other Types of Bonds**
- Metallic Bond
- Hydrogen Bond
- Van der Waals Forces
**Ionic Substances**
Ionic substances result from electrostatic forces holding ions in a rigid, well-defined, three-dimensional structure. They are usually solid with

Chemistry: A Physical Science
Science is the knowledge obtained by observing natural events and conditions to discover facts and formulate laws or principles. Chemistry is the study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes. A chemical is any substance with a definite composition.
Branches of Chemistry
- Organic Chemistry: The study of materials with carbon.
- Inorganic Chemistry: The study of non-organic
