Due to their radioactivity, antimony-124 and antimony-125 are used as tracers. For example, antimony-124 is used in oil pipelines, where its movement can be traced. This is particularly useful as it can help to identify leaks, if the tracer moves out from the pipe (Chemistry explained, n.d.). Uses Highly purified antimony plays an important role in semiconductor technology, specifically for diodes and infrared detectors that react to infrared radiation (Encyclopaedia Britannica, 2009). Antimony is commonly used to make allows and perhaps the most notable are lead-antimony alloys which have various uses. These uses include solder, ammunition, fishing tackle, covering for electric cables and batteries (Chemistry explained, n.d.). Compounds Compounds of antimony that are used include antimony oxychloride (SbOCl), antimony pentoxide (Sb 22 O55), antimony trichloride (SbCl3), and antimony trioxide (Sb22 O33 ) (Chemistry explained, n.d.). Antimony trioxide is commonly used in paints and well as various textiles, rubber and plastics allowing them to become flame retardant. An organic salt of antimony known as tartar emetic is used to help bind dyes to fabrics, making it important in the textile industry (Encyclopedia Britannica, …show more content…
It is semi-metallic, existing in both a metallic form which is silvery, hard and brittle, and in a non-metallic form. When it is in this form it is a grey powder (Lenntech, n.d.). Antimony is a metalloid, therefore it has the characteristics of metals and non-metals. As a material it is fairly soft and able to be scratched by glass. It has a density of 6.68 grams per cubic centimetre. As for its chemical properties, antimony is described as moderately active and does not combine with oxygen in the air. Antimony does not react with cold water or acids, however, it does dissolve in some hot acids. It is also a poor conductor of heat and electricity (Jefferson Lab,
It absorbs and reflects light, including ultraviolet radiation from the sun, which can cause products to worsen and lose their pigment. Talc, hydrous magnesium silicate (MgSlO4) is used as an absorbent, anti-caking agent. It improves the feel of the product and helps smooth or soften them. Metallic stearates (C17H35CO) also known as stearate salts are used for their moisturizing properties. They help keep the mixture of two or more liquids from separating into their oil and liquid components. The stearate salts increase the thickness of the liquid and reduces the transparent appearance of finished products. Lecithin (C42H82NO8P) or hydrogenated lecithin help cover the appearance of dry or damaged skin by reducing flaking and restoring flexibility. It also has skin-restoring abilities. Sulfosuccinate (C20H37NaO7S) helps the water solubility of other cosmetic ingredients. It also helps form the unblendable mixtures by reducing the surface tension of the substances, which is known as a cleansing agent. Ethoxylated alcohol (C26H50O10), functions as a surfactant and are used as cleansing agents. They clean the skin by helping water mix with oil and dirt so they can be washed away. It also acts as a skin conditioning agent. Bentonite (Al2O34SiO2H2O) has many purposes. It 's used for smoothing, polishing, or abrading other chemicals in the foundation. Helps hold together all of the ingredients. Acts as an absorbent. Increases the volume of a
The purpose of this experiment was to classify unknown solids based on their type of chemical bonds by investigating their properties. By using data, Unknown 1 was classified as a metallic. This was because it appeared a shiny copper color, had a very high conductivity as a solid, had a high melting point, and was malleable. Unknown 2 was classified as a nonpolar covalent bond. This was because it had no conductivity as a solid and low conductivity in water.
Ansul fire suppression systems use clean agents that quickly vaporize to a gas when used. The product evaporates without leaving a residue behind, and the chemicals are designed not to deplete any ozone and have a small atmospheric lifetime. The FE-36 agent is approved by the Environmental Protection Agency (EPA) for industrial, commercial, and military use via the EPA’s SNAP program that evaluates substitutes for ozone-depleting substances. This product is even safe to use in art galleries.
used for dental fillings for cavities. Subsequently in 1898, it was found to be radioactive.
It is used for heating chemicals, boiling water, sterilizing small objects, preparing microscopic slides, bending glass tubing, and several other things. He also found a cure for arsenic poisoning but after 6 years of working with it he lost sight in one eye from an explosion and also nearly killed himself from arsenic poisoning. He also was the first person to ever obtain magnesium in its metallic state and study its physical and chemical
As said before, Krypton is used in some types of photographic flashes, some fluorescent bulbs, and its mixtures are used in signs to give them a greenish-yellow glow. It was also once used in measurements and is used in lasers for lab use.
While it seems metallic and glossy, it starts to consume promptly in air because of the dampness introduce.
For example, Mercury was used in thermometers, barometers and diffusion pumps. It was also used in fluorescent light bulbs and batteries. Mercury is still used for dentistry purposes and also to extract gold. Mercuries amalgam is used to dissolve the gold and then separate them for distillation.
According to Silver (n.d.), the characteristics of silver is that it is a soft, white metal that occurs in nature in four forms. The first form is as a native element. The second is as a primary component in silver materials. The third is as a natural alloy with other metals. The fourth is as a trace to minor components in
In subsequent centuries it had military applications in rifles and cannons, but in these it has long since been replaced by modern, smokeless powders. The fireworks industry is one of the last major industries that still uses traditional black powder.
They can be found in/are paint thinners, fingernail polish remover, degreasers, dry-cleaning fluids, gasoline, contact cement, hairspray, spray paint, deodorant spray, vegetable oil sprays, and fabric protector spray, Butane lighters, propane tanks, whipped cream dispensers, refrigerant gases, and anesthetics.
To begin with, germanium is used in the manufacture of wide-angle camera lenses. The element gives special properties to the glass. Since, germanium has traits that are similar to silicon and tin, the semiconductor industry uses germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps. In other words, germanium is used to make camera lenses for electronic
Arsenic has an atomic number of 33 and a relative atomic mass of 74.922amu. Arsenic is an odd element, as it acts like metal even though it is a natural element. Arsenic is found in natural environments, and in limited quantities found in rocks, soil, water and more. Arsenic was very known to the ancient Egyptians and the Chinese, they used Arsenic as a way of gilding metals. The orpiment(As2S3) and the realgar (As4S4) : are the two Arsenic sulphide minerals that Greek Philosopher, Theophrastus. As2O3 is the trioxide, is one of the end products of copper refining. This is a form of arsenic that has also been known for awhile now, and it is called white arsenic. The official discovery of arsenic is to Alberts Magnus in around the 1200s. As to the physical property, it is radiant, has a silver colour and fragile, as it is a semi-metal. When in exposed to air, it is rapidly damaged, because of the usual elements in air, such as nitrogen and more. Arsenic is not particularly used in any technology, but recently we use Arsenic in semiconductor gallium arsenide, it can convert electric currents to laser lights. Usually it is not used
45Sc is used in oil refineries as a tracing agent.Scandium is not freely found in nature but can be found combined in minute amounts of 800 materials.The rare minerals from the areas Scandinavia and Madagascar are the only known concentrated sources of the element.
It’s used for other things though like manufacturing high-voltage indicators, television tubes, wave meter tubes and lightning arrestors. It is commercially used as cryogenic refrigerant. It can create exotic compounds with fluorine in laboratories, being an inert element.
