Introduction According to the Columbia Encyclopedia, sodium tetraborate decahydrate (also known as borax) is a chemical compound that is slightly soluble in cold water but very soluble in hot water (“Borax”). Some of the various uses of borax are a cleansing agent, an antiseptic, occasionally as a preservative and used as a flux for silver soldering. The purpose of the experiment was to determine the thermodynamic quantities, enthalpy (ΔH°) and the standardized entropy (ΔS°) of the solvation of
Ribonucleic acid is a large part of the modern world as RNA (Ribonucleic acid) is one of the major macromolecules which are known for playing an essential role in all known forms of life. The most common function of RNA is that it is a copy of DNA and is used to create proteins and other organic compounds. To produce a certain protein, it activates the area of DNA that codes for a specific protein needed. Thus it replicates that section of DNA in the form of messenger RNA. Ribosomes are then used
found in large deposits in the W United States (Borax Lake in Death Valley, Calif.; Nevada; and Oregon). Borax can also be obtained from borate minerals such as kernite, colemanite, or ulexite. Recipes for homemade “green” cleaning products often contain a common ingredient such as borax. But borax is a white, powdery mineral also known as boric acid, sodium borate, sodium tetraborate, or disodium tetraborate it can be toxic Borax and things like that are to cause irritation to skin, and the eyes.
Christmas list that year. People ask why slime is made because in the background slime is a unique play material composed of a cross-linked polymer. It is classified as a liquid and is typically made by combining polyvinyl alcohol solutions with borate ions in a large mixing container. It often has an unpleasant odor, a green color, is cold and is slimy to the touch. The world also asks “Is slime a liquid or solid.” Slime is a non-Newtonian liquid, which means that the viscosity, or resistance,
than linear polymer, which is glue by itself (Discovery center). What makes slime stretchy and thick? The glue has flexible molecules in it called polymers, they slide past each other as liquid. Borate ion (B(OH)4- is borax in water forming the ion. When the solution (borax) is added to the glue, the borate ion help connect the polymer molecules to each other so they won't be able to move and flow as easily. When enough polymer molecules gets absorbed together correctly, the glue changes for liquidity
in silicates, borates, phosphates, germanates, tellurites, boro alluminate, alumino silicates, borotellurate etc., glasses. It is also observed that properties related to cationic movement are more sensitive to mixed alkali effect [1-3]. Alkali oxy borate

What went wrong also needs to be determined through the chemistry involved in maintaining a pool. Normal Pool Chemistry: The water in pools has to be disinfected to make it safe for swimming. But the disinfectants added to pools aren’t just killing harmful microbes. They’re also reacting with organic
Preventing termites is likely a number one concern for homeowners. Termites are small but they are capable of costing homeowners billions of dollars each year statistics reveal. A termite infestation happens in every corner of the US, but mainly in homes where people use artificial heating. On an average, there could be up to 14 termite colonies for each acre of land. With this said, it's possible a dwelling could have an average of four colonies under the property or at least around the home
Flame retardant properties Chemically all polymeric materials comprise of hydro-carbon chains and usually have high heat of combustion. When they are exposed to fire, they burn rapidly with the release of high amount of heat, flame and smoke. Similarly the natural fibers, wood flour, are highly combustible and burn rapidly. So for safely use of the composites materials they must have flame retardant properties as well. The burning of the materials is a complex process. Combustion of any material
Slime is a special play material made up of tangled polymer. It is mostly made by mixing polyvinyl with the chemical compound known as borate ions, you can describe it as a liquid and mix it in a sizable container for mixing. In a more difficult explanation, slime is more commonly known amongst scientists as a Non-Newtonian fluid. These are thick liquids that have a numerous selection of viscosity. Slime, has a different viscosity, based on the amount of strength you apply when playing with it.

molecule of fructose. Isomerization of lactose can be accomplished using chemical or enzymatic methods. Chemical methods employ an alkaline catalyst, such as sodium hydroxide or potassium hydroxide, in combination with a complexing agent, such as borate or aluminate, that will attach to lactulose and precipitate as an insoluble complex from the reaction system, thus shifting chemical equilibrium in favor of the formation of the lactulose product; lactulose synthesis by this method can result in up
1.1 Capacitors A capacitor is a device contained by an electric circuit, which stores electric charge. They are commonly used in computers, televisions and all electronic circuits such as car ignition circuits and some electric power tools. They play a significant role in electronic circuits, such that without capacitors the will be a limitation of electronic circuits. Capacitors do not have the ability to conduct electric charge like other components of the circuit do, but can store the electric
Boron is one of the many elements on the periodic table. Its atomic number is five and its symbol is the letter B. Boron’s atomic weight is 10.811. It is a solid at room temperature. The group number for Boron is 13 and the periodic number for Boron is 2. It is also in the p block. Its element category is a metalloid. Boron came from the Arabic word Buraq and the Persian word Burah, which are both meanings for the material called “Borax.” Boron is a tough element – very hard, and very resistant
Australia was formed, in the year 1966 the first exports to Japan, in Western Australia Rio Tinto launched it’s iron ore operations with the launch of Hamersley iron mount from price mine. Owners of the world largest deposit of industrial mineral borates, that has hundreds of everyday uses Borax was acquired by Rio Tinto in 1968. Things went bad for Rio Tinto when it’s participation in Cornwall’s ancient tin mining industry in the United Kingdom ended due to declining demand and prices for the metal
Nearly every person in the world uses salt or some form of a salt as there are many salts in the world. In America alone we use a lot of salt every day we are one of the top salt using countries in the world. Salt has a part in many things in everyone’s daily lives. Salt has many important things to it such as its crystallization, what salt is and ammonia. Each type of crystal has its own properties and shapes. Crystals are an organized arrangement of atoms and molecules. The atoms sodium (Na) and
are extremely sharp. If millipedes walk through diatomaceous earth, it cuts their body and causes it to dehydrate. As they dehydrate, they start to die. Another technique is to use boric acid. This weak acid is made from a natural mineral known as borate. Sold in a powder form, it dries out the millipede's body like diatomaceous earth does. Wood ash from your oven or outdoor stove can be used to dry the millipede's body quickly and easily. Put it on the soil near your foundation, and the millipedes
The Ottoman Empire started as a small Turkish state and turned out to be something major. However, this Empire was one of the biggest empires in history. The Ottoman Empire had many problems along the way. The Ottoman Empire’s features and foundation lead to the growth, but the Empire still fell. The Ottoman Empire was one of the World's Largest Empires. The Ottoman Empire is also referred to as the Turkish Empire. It is the most powerful and long-lasting empire in history. The Ottoman Empires primary
Copper and copper alloys are widely used in the aqueous environmental application because of their properties in such environment, copper and copper alloys are antimicrobial, they are also have strong mechanical and corrosion resistant properties in aqueous environmental. The combination of these properties has made them a desirable material for many kind of aqueous environmental applications such as condenser tubing, water intake screens, offshore structure, drinking water piping and cooling systems
