      What Are Pennies Made Of?

      Before 1982, the penny was made of copper which is why they, unlike most other coins, don't look silver. However, after 1982, the U.S. government realized that it was too expensive to make a penny–more than the penny was worth in money–so they decided, instead, to make it with a mixture of two different metals.

    • What is Magnesium Used For?

      What is Magnesium Used For?

      Magnesium is a chemical substance denoted by the symbol Mg. It forms part of the Group 2 of the periodic table, thus making it an alkaline earth metal. Its atomic number is 12 and it is considered to be the 8th most copious element found in the earth’s crust. In terms of the human body,

    • Potassium Benzoate

      Potassium Benzoate

      Potassium benzoate is the potassium salt of benzoic acid. Benzoic acids are weak acids that are used as food preservatives. Potassium benzoate is also commonly used for preserving food. It is primarily used to inhibit mold and bacteria growth. This allows the product that potassium benzoate preserves to last longer on the shelf, thereby increasing

    • Potassium Carbonate Dihydrate

      Potassium Carbonate Dihydrate

      Potassium carbonate dihydrate (K2CO3.2H2O) is a white chemical. Salt from potassium carbonate and water from the dihydrate are mixed into a deliquescent (wet salt). It is a strong alkaline solution that garners a variety of uses. The salt tastes like salt and alkaline material. Potassium carbonate dihydrate is generally used as a nutritional supplement in

    • What is a Polyolefin?

      What is a Polyolefin?

      One of the largest classes of organic thermoplastic polymers is polyolefin. Polyolefin is an odorless, non-polar, and non-porous material that is used in structural plastics, consumer goods, industrial products, and food packaging. Polyolefin means “oil like” and is commonly referred to as a thermoplastic or polyalkene since polyolefin has a waxy texture. This substance is

    • What Are Ionic Compounds?

      What Are Ionic Compounds?

      An ionic compound is any compound in which an electrostatic force holds the ions together. Ionic compounds are made of positively charged particles that rest against negatively charged particles in order to balance out the two particles’ magnetic imbalance. They can be found in both solid and liquid states, although solid ionic compounds are poor

    • What is Acesulfame Potassium?

      What is Acesulfame Potassium?

      Acesulfame potassium (Acesulfame K or Ace K, where “K” is the elemental symbol for potassium) is commonly used as an artificial sweetener or flavor enhancer. It is used in low calorie food products as it replaces sugar and other natural sweeteners that commonly add large amounts of calories. Acesulfame potassium’s trade names include “Sunett” and

    • Isobutane

      Isobutane

      Isomers are compounds with the same molecular, but different structural formulas. Isobutane is an isomer of butane. It belongs to a class of compounds called alkanes, which are chains of carbon atoms where each carbon atom is attached to as many hydrogen atoms as possible.  Its chemical formula is C4H10. Butane consists of four carbon

    • What is a Plasma Cutter?

      What is a Plasma Cutter?

      A plasma cutter is a device that directs an ionized gas at an object under extreme temperatures. Plasma cutters are often used for industrial purposes, such as cutting metal, and are dependent on plasma, an extremely hot state of matter. Plasma cutters are essentially a type of plasma torch meant for cutting metal rather than

    • What is FTIR Spectroscopy?

      What is FTIR Spectroscopy?

      FTIR spectroscopy (Fourier Transform Infrared Spectroscopy) is a technique that uses infrared light to observe properties of a solid, liquid, or gas. It is used in many different applications to measure the absorption, emission, and photo-conductivity of matter by shining a narrow beam of infrared light at the matter in various wavelengths and detecting how
