Lithium Name: Lithium Atomic number: 3 Atomic Weight: 6.941 grams/mole Group in periodic table: 1 Group name: Alkali metal Color: Silvery white/grey Lithium is solid only about half as dense as water and lithium metal is the least dense metal. Lithium is known as losing its electron‚ so it becomes Li+. Lithium is mixed with aluminum and magnesium for light-weight

Summary Researchers typically use a batch reactor to study reaction kinetics under ideal conditions. This experiment was carried out in other to study effect of temperature on reaction rate constant and also to study the effect of the reaction rate constant in a batch stirred tank reactor its important in chemical industry because it is used to determine the effect of temperature on reaction rate constant; it is also used in chemical and process industry for solids dissolution‚ product mixing‚ chemical

AIM The aim of this investigation is to explore the effect of different concentrations of bile salts on the time taken for the lipase enzyme to break down fat. BILE Bile is a brownish bitter alkaline fluid produced by the liver and made by the hepatocytes from water‚ bile salts‚ bile pigments cholesterol and phospholipids and stored in the gall bladder. Bile is directly connected with digestion. It is released sporadically into the small intestine (duodenum) which is part of the gut in order

Creation of Oahu by Volcanism Karen Ta: 430 BOT 450 TR 10:30-11:20 Volcanoes are magnificent formations from an opening in a planet’s crust. They form when magma‚ volcanic ash‚ and gases escape from a magma chamber below the surface of the planet. Tectonic plates cover the surface of the planet and are constantly moving. Volcanoes are generally found where these plates converge or diverge. Not only are volcanoes found in these areas but also where the Earth’s crust is stretching or thinning

oxygen concentrations‚ moisture levels‚ hydrostatic pressure‚ osmotic pressure‚ and radiation levels. When considering the pH level‚ bacteria are classified as either acidophiles (acid-loving)‚ neutrophiles (neutral ph range)‚ or alkaliphiles (alkali-loving). The one that causes disease in humans would be the neutrophiles‚ which have an ideal pH range of 5.4 to 8.0. There are exceptions‚ however‚ like Alcaligenes faecalis and Vibrio choleae‚ which are both alkaliphiles and can infect humans

an ether bond opposed to an ester bond in their phospholipid bilayer membrane which surrounds the cell. This ether linkage is chemically far more resistant than the ester linkage‚ allowing the archaeon to be far more resistant to extreme acidic or alkali environments and high temperatures and so on. However‚ in this sample of sediment from the Marianas Trench‚ the DNA of Pseudomonas‚ a genus of bacteria‚ was found along with other marine Archaea DNA: so even though Archaea are better adapted to chemically

larger and greater specifications are desired. The initial step of metallurgy should be to create aluminium oxide. In alumina oxide production with sintering process‚ we need to first create the raw materials compounded by bauxite‚ limestone and alkali into clinker. The sintering process is completed within the vertical roller mill whose inner temperature is 1300℃. The final phase of aluminium oxide manufacturing is to roast aluminum hydroxide into alumina oxide. The inner temperature is about 1200～1250℃

The status and characteristics of China’s cement industry are large output‚ high kiln temperature‚ fast kiln speed‚ heavy alkali corrosion‚ complex structure and high energy efficiency requirements. In the last year China’s cement production hit a new record of 1.868 billion tons. It is expected that this year the demand on cement market will remain strong and the production

polymerization of propylene. There are three main grades of polypropylene produced: homopolymer‚ co-polymer‚ and impact co-polymer. Polypropylene possesses intrinsic properties of high stiffness‚ good tensile strength‚ and inertness toward acid‚ alkalis‚ and solvents‚ which makes it suitable for applications in various industries such as Packaging‚ Automotive‚ Consumer Goods‚ Construction‚ and Electrical and Electronics.
