The saponification (a reaction in making soap) process is a base (usually NaOH or KOH) hydrolysis of triglycerides to make salt (soap) and glycerol. Alkalis such as Sodium carbonate and Sodium hydroxide are used to neutralize the fatty acid and convert it to a salt. The molecules crystallize differently depending on the base used. NaOH produces a harder bar while KOH is used more frequently for liquid soaps. In some cases, Lithium soaps are formed and produce much harder soaps. There are four

Polar bears have a thick layer of fat called blubber which is about 11 cm thick. This also helps the bears to survive in the freezing conditions. Not only on land, but the thick layer of fur coat and blubber helps them as they spend a great amount of time swimming in the freezing waters of the Arctic. Blubber is a thick layer of fat that helps prevent sea mammals from getting too cold. Blubber in depth, is an extra digested food stored in the form of adipose tissue, which contains molecules called
season, recover the finished product. This is a local distribution. In the domestic system, there is a part of the textile industry, spinning and weaving (flax and hemp in Northern France and Picardy silk in Lyon) and the metallurgical industry, iron + cast iron blast furnaces and watches (Jura, Switzerland) Merchant-manufacturers will gradually bring the workforce in one place to better manage, supervise and often to be closer to the raw material. The birth of these workshops will lead to the creation
Persuasive Paper Hello, and welcome to my store! I will shape and carve all of your black metals into usable everyday household items such as: weapons, armor, tools, and hardware. I use these objects called anvils to shape the iron and steel. I remember the first time when I arrived in America and my parents sent me to apprentice a blacksmith. I had such great memories of my childhood until the King started to tax us. When I started this business, the Navigation Acts wrecked it. I have to pay England
a blue-green oxidized surface. The Statue of Liberty is a prime example of oxidized copper. The oxidized surface consists of insoluble ionic compounds of copper (II) oxide and copper (II) carbonate. In class, we did an experiment with where we changed copper into its different states. For example, we added sodium hydroxide to copper (II) nitrate. We turned the copper into a
1892. The ironing board was invented to make it easier for a person to iron clothes. Ironing was around for a long time before the ironing board was invented. For example, the first known ironing boards were used by the Vikings in the 9th century. They would use whale bone ironing boards and very smooth glass as an iron. the glass did not get hot. It was just very heavy so it could flatten surfaces. For example, chinese pan irons were used by 2 people stretching cloth in mid air while one person ironed
on the idea that Abraham Darby perfected the technique of smelting iron with coke, in Coalbrookdale, allowing much cheaper production of iron. However, the industrial revolution did not "begin" in one place, but in many. Smelting iron by Darby was but one small part of this generalised revolution and was soon superseded by the great iron-smelting areas. However, the bridge – being the first of its kind fabricated from cast iron, and one of the few which have survived to the present day – remains
scrap metal company in the U.S. that processed about 3.5 million tons of scrap iron and steel annually. With the acquisition, Nucor also acquired the DJJ Rail Services business that owned over 2,000 railcars that moved scrap materials, offered railcar fleet leasing services. Supplies its own direct reduced iron – In 2004, Nucor purchased assets from a plant in Louisiana that converts iron ore pellets into direct reduced iron. This has provided Nucor with a large supply of DRI to produce more demanding
Industry brief: The steel industry is one of Australia’s largest and most profitable industries. In 2010, iron ore overtook coal as Australia’s most valuable export – $47.2 billion worth left our shores (The Conversation, 2011). It is Australia’s most successful financial industry and it is a significant contributor to the Australian economy. BlueScope steel is also one of Australia’s most successful steel companies. Its main focus is construction and the manufacturing of steel based products. The
The aluminum 3104-H19 alloy also has some other important properties that make it a suitable material for pop cans. One of the most important properties this alloy has is corrosion resistance. This means that the aluminum alloy can hold a liquid for extended periods of time with no corrosion occurring. If the aluminum alloy was not corrosion resistance, the liquid contained inside would corrode the inner walls of the pop can and lead to eventual fail of the pop can. Due to the fact that this
How has the extraction of metals changed the course of history? Metal: Magnesium Magnesium is a metal that is both industrially and biologically important. It is the lightest structural metal that is currently available for us. Its other advantages include excellent fatigue, denting and damping resistance. Therefore it is used commonly in alloys for car and airplane construction, electronics, luggage and power tools. It is also used in fireworks and sparklers, as it is easy to ignite and burns
Mining is one of Canada’s primary industries, it involves extraction, refinery, and the processing of valuable minerals such as gold, copper, iron, nickel and zinc. All of the provinces except Prince Edward Island has had significant mining activities, but the industry is concentrated in provinces like Ontario, Quebec, Saskatchewan and British Columbia. Although mining is key to Canada’s economy, the country had been criticized for its methods of extraction of the minerals since it has negative
One of the heavy metal occurs naturally in earth as a form of rocks and can be found from the earth’s crust is called uranium. It is used as various sources of concentrated energy such as nuclear power, electricity and others. German scientist named Martin Klaproth discovered this important element in 1789(“What is uranium? How does it work?”, 2014).Today, Australia take a major part of the uranium industry and its reasonably assured resources of uranium is one of the world which is approximately

Concrete is the primary material in construction industry. It consists of cement, coarse aggregate, fine aggregate, water and other admixtures. Generally Ordinary Portland cement is used in concreting but the production of OPC causes a huge amount of carbon emission and also it uses a huge amount of non-renewable natural resources. The concrete construction practice in use is considered as unsustainable because it consumes a huge quantity of sand, stone and water and 2.5 billion tons of OPC per year
From the brown appearances of the bowls, they are likely to be Changsha wares. Since they were often associated with motif painted with iron brown and copper green pigment. Although some wares were shattered in this shipwreck, some of it survived in one piece. The darker brown painted at the sides on the bowl might seem decadent. But they are still in relatively good form even till today
The main Se indicator plants are prince's plume (Stanleya sp.), woody asters (Xylorhiza sp.), Astragalus species (including some locoweeds), and false goldenweed (Oonopsis sp.) (Gregory and Vadim, 2004). Inside the plants, Se is transported through sulfate transporters which are present in the plasma membrane of root cells. Through sulfur metabolic pathway it is assimilated to organic Se and volatilized as DMSe (Dimethylselenide) and DMDSe (Dimethyldiselenide) into atmosphere. ( Meetu and Shikha
bedrock and soil. Chromium weathered from the rocks is deposited on the soil and groundwater. Chromium is also generated anthropogenically from various industrial processes which includes electroplating, leather tanning, wood preservations, manufacturing of dye, paint, paper, petroleum refining processes, metal finishing, alloysteel manufacturing, and lasers(Owlad et al., 2010). According to BIS (Bureau of Indian Standards) and USEPA the maximum acceptable limit for Cr(VI) in drinking water is 0
