Mercury is a liquid metal that was named after the Roman god Mercury. It has an atomic number of 80 and average atomic mass of 200.59. Mercury has 6s valence electrons and is classified uniquely as both a metal and liquid. It has many uses in thermometers and scientific tools due to its properties, but is also highly toxic to humans and can cause severe illness or death if exposed. Mercury was known and used in ancient Egypt and other ancient civilizations, and remains the only metal that is liquid at standard temperature and pressure.

Study of Dyeing of Cotton Fabric using Peanut Pod Natural Dyes using Al2So4 C...Agriculture Journal IJOEAR
— The decline in the use of artificial colourants due to their toxicity in food and textile industry, put forward by international market has increased the importance of natural raw materials. From those, peanut pod (Arachis hypogaea) with solid applications is one of the most important sources of natural dyes. The major colouring component in peanut is pods, extracted from the fresh and dried peanut pod. The aim of present work is to evaluate peanut pod powder as natural textile dyestuff. The work consists of three steps, i.e. extraction, characterization and dyeing processes. The dye extraction procedure is conventional and traditional. Dyeing of cotton fabrics with the extract of peanut pod powder has been carried out and dyeing has been optimized using three mordanting agents as: Alum, Copper Sulphate and Ferrous Sulphate. Finally, dyed fabric have been subjected to different textile laboratory tests e.g., colour fastness, light fastness, washing fastness and rubbing fastness (dry and wet).Glacial ice powerpoint
Glacial ice is the largest reservoir of freshwater on Earth and supports one third of the world's population. Glaciers form on land where snow accumulation exceeds melting. They slowly deform and flow due to their own weight, creating features like crevasses. Glaciers erode the underlying landscape through abrasion and plucking of rock debris. As they carry this debris and later melt, glaciers leave behind landforms such as moraines, eskers, and drumlins that provide evidence of past glacial activity. Glacial periods within ice ages are marked by colder temperatures and advancing glaciers, while interglacials are warmer intervals between them.

Presentation on fabric
This document discusses different types of fabrics, including natural fabrics like cotton, silk, linen, jute, and wool that are formed by nature, as well as man-made fabrics like polyester, rayon, denim, vinyl, fiberglass, and polyethylene. It describes fabrics as materials that can be used for garments, shoes, carpets, and more, and notes they come in two forms - woven fabrics or non-woven fabrics. The document also lists some common applications of fabrics, such as for clothing, dust collection, construction sites, industrial uses, and daily items.
Cellulose and it's properties
The document discusses cellulose, including its structure, properties, production in plants, and uses. Some key points:
- Cellulose is the most abundant organic substance on Earth and is made of linear chains of glucose molecules linked together.
- It has a crystalline structure that gives it strength and it forms microfibrils in plant cell walls.
- Plants produce cellulose at their plasma membranes using enzyme complexes that spin the cellulose chains.
- Cellulose is strong, stable, and insoluble but can absorb some water. It is used to make products like cotton, paper, cellophane, and cellulose derivatives.
bioaccumulation and
Bioaccumulation and biomagnification refer to the increasing concentration of pollutants like pesticides, mercury, and other chemicals as they move up the food chain. Bioaccumulation is when an organism absorbs more of a substance than it eliminates, resulting in increasing concentration over time. Biomagnification occurs when concentrations increase at each trophic level, so organisms at the top of food chains face greater exposure. Pollutants like DDT, PCBs, and mercury are especially prone to bioaccumulation and biomagnification due to their persistence and ability to concentrate in fatty tissues. This can negatively impact wildlife and pose risks to human health through consumption of contaminated fish and seafood.

Mercury has an atomic number of 80, atomic mass of 200.6, and chemical symbol of Hg. It exists as a liquid at room temperature and has six stable isotopes. Mercury was known in ancient times and gets its name from the Roman messenger god due to its liquid state. It melts at -38.83°C and boils at 356.73°C. Mercury is commonly found in thermometers and electrical applications due to its conductive properties and forms amalgams with gold. It can bond ionically with metals like gold, zinc and iron but not with tantalum, tungsten or platinum.
Mercury - Hg
Mercury is a heavy, silvery-white liquid metal that was used in ancient times but is now known to be toxic. It has a low melting point and is the only metal that is liquid at standard temperature and pressure. Mercury was used for religious and medical purposes historically but is now primarily used to manufacture chemicals and in electrical applications like fluorescent lights, though some uses are being phased out. While mercury's physical properties allow it to be walked on, exposure to its vapor leads to health problems.

Mercury is a highly toxic liquid metal that is poisonous to humans. It is located in Period 6, Group 12 of the periodic table. The ancient Chinese and Hindus were among the first to discover mercury in Egyptian tombs in 1500 BC. Mercury is named after the Roman god Mercury and is commonly found in coal deposits. It is used to make thermometers, lamps, batteries, and dental preparations due to its low melting point, but its toxicity requires safe handling.

Visual encyclopedia of the elements
Everything in nature is made up of simple substances called elements, which are the basic building blocks. There are 118 known elements, 92 of which occur naturally. Elements are rarely found in their pure forms and usually combine to form compounds. The periodic table organizes the elements and provides key information about each one, such as properties and classification. Scientists have been studying elements for thousands of years, from ancient Greek philosophers who proposed that all matter was made of four elements, to modern chemists who have discovered 118 so far through experiments and new technologies.
