  2. Salt (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Salt_(chemistry)

    In chemistry, a salt is a chemical compound consisting of an ionic assembly of positively charged cations and negatively charged anions, which results in a compound with no net electric charge. A common example is table salt , with positively charged sodium ions and negatively charged chloride ions.

  3. Force field (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Force_field_(chemistry)

    Force fields are interatomic potentials and utilize the same concept as force fields in classical physics, with the difference that the force field parameters in chemistry describe the energy landscape, from which the acting forces on every particle are derived as a gradient of the potential energy with respect to the particle coordinates.

  4. Blood alcohol content - Wikipedia

    en.wikipedia.org/wiki/Blood_alcohol_content

    For example, a BAC of 0.10 by volume (0.10% or one tenth of one percent) means that there is 0.10 g of alcohol for every 100 mL of blood, which is the same as 21.7 mmol/L. A BAC of 0.10 by mass (0.10%) is 0.10 g of alcohol per 100 g of blood (23 mmol/L).

  5. Anabolic steroid - Wikipedia

    en.wikipedia.org/wiki/Anabolic_steroid

    Most steroid users are not athletes. In the United States, between 1 million and 3 million people (1% of the population) are thought to have used AAS. Studies in the United States have shown that AAS users tend to be mostly middle-class men with a median age of about 25 who are noncompetitive bodybuilders and non-athletes and use the drugs for cosmetic purposes.

  6. Shower gel - Wikipedia

    en.wikipedia.org/wiki/Shower_gel

    In 1865, William Shepphard patented the formula behind the liquid soap, but the product gained eventual popularity with the rise of Palmolive soap in 1898, by B.J. Johnson. Modern chemistry later [when?] enabled the creation of the shower gel, which specialized in cleaning the entire body during baths and showers. Properties

  7. Copolymer - Wikipedia

    en.wikipedia.org/wiki/Copolymer

    An alternating copolymer has regular alternating A and B units, and is often described by the formula: -A-B-A-B-A-B-A-B-A-B-, or -(-A-B-) n-. The molar ratio of each monomer in the polymer is normally close to one, which happens when the reactivity ratios r 1 and r 2 are close to zero, as can be seen from the Mayo–Lewis equation.

  8. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    Sodium carbonate, Na 2 C O 3, (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na 2 CO 3 and its various hydrates. All forms are white, odourless, water-soluble salts that yield moderately alkaline solutions in water.
