BaZnGa T-shirt design. BaZnGa (barium zinc gallide) is a ternary compound of barium, zinc, and gallium that was inspired by the saying "Bazinga!" from Sheldon Cooper on The Big Bang Theory television series. [1] It is a poor metal. BaZnGa crystals can be grown by adding gallium to a BaZn eutectic at 800° C and then cooling to 400 °C. Hot ...
Jim Parsons is known mostly for his incredible portrayal of the socially awkward theoretical physicist, Sheldon Cooper, on the CBS smash hit "The Big Bang Theory". His "Sheldonisms" circulate on ...
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.

ACS grade is the highest level of purity, and meets the standards set by the American Chemical Society (ACS). The official descriptions of the ACS levels of purity is documented in the Reagent Chemicals publication, issued by the ACS. [3] [4] It is suitable for food and laboratory uses. Reagent grade is almost as stringent as the ACS grade.
The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
