Which of the following is man made silicate
A large number of man-made silicates exist nowadays: Inorganic binders like cement and water glasses, catalysts made of synthetic zeolites, organosilicate compounds such as tetraethyl orthosilicate (TEOS) which is commonly used as a precursor in the sol-gel processing, etc….
What are the 2 most common silicate minerals
Feldspar and Quartz Feldspars are by far the most common silicate mineral, making up more than half of the earth’s crust.
What is silicates and its types
Silicate minerals are the most common of Earth’s minerals and include quartz, feldspar, mica, amphibole, pyroxene, and olivine. Silica tetrahedra, made up of silicon and oxygen, form chains, sheets, and frameworks, and bond with other cations to form silicate minerals.
Which is Pyrosilicate
A pyrosilicate is a chemical compound that contains the phyllosilicate anion Si2O6-7 with the hexavalent group −(O3Si-O-SiO3)− . … this units joined together by the removal of oxygen and two units then join at the corners of oxygen atoms.
What are the uses of silicates
Silicates and silicate-based compounds are frequently used materials in dentistry. One of their major applications is their use as fillers in different dental filling materials such as glass-ionomer cements, compomers, composites, and adhesive systems.
Which is the largest cell
ovumThe largest cell is ovum in the human body. The ovum also called egg cell is the reproductive cell in the female body. Ovum is 20 times bigger than the sperm cells and has a diameter of about 0.1 mm.
How silicates are formed
Phyllosilicates, or sheet silicates, are formed when three oxygen atoms are shared with adjoining tetrahedrons. The resulting infinite flat sheets have unit composition Si2O5. In structures where tetrahedrons share all their oxygen ions, an infinite three-dimensional network is created with an SiO2 unit composition.
How many types of silicates are there
Of the approximately 600 known silicate minerals, only a few dozen—a group that includes the feldspars, amphiboles, pyroxenes, micas, olivines, feldspathoids, and zeolites—are significant in rock formation. The silicates, owing to their abundance on Earth, constitute the most important mineral class.
Which one of the following anions is basic structural unit of silicates
The basic unit for all silicate is SiO4-4.
Which of the following is basic unit of Orthosilicate
Structure. The orthosilicate ion or group has tetrahedral shape, with one silicon atom surrounded by four oxygen atoms. In the anion, each oxygen carries a unit negative charge. The Si–O bond is 162 pm long.
What is the example of silicate mineral
The vast majority of the minerals that make up the rocks of Earth’s crust are silicate minerals. These include minerals such as quartz, feldspar, mica, amphibole, pyroxene, olivine, and a great variety of clay minerals.
What is the basic structural and functional unit of an organism
The cell (from Latin cella, meaning “small room”) is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. Cells are often called the “building blocks of life”.
What is SiO4 called
oxygen tetrahedron has a net electrical charge of -4: (SiO4)-4. Since minerals are chemical compounds which can not have an electric charge, this charge is balanced by the addition of metals, which are all positively charged.
What is the basic structure of an organism
Cells make up the basic structure of an organism, and they perform basic life functions for the organism. Cells make up the basic structure of an organism, but they do not perform basic life functions for the organism.
What is the name of functional unit
Answer. Explanation: Cells are called the structural and functional unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells.
