### binary digits:

Machine code
* is binary digits
  - code
  - computer code
  - considered the first generation of programming languages
  - source code
  - what assemble code
* refers to the program instructions in hexadecimal form.
  * An instruction tells the computer to do one thing. The operands are usually memory addresses. An instruction set list of the opcodes used in a computer. Machine code is what assemble code. Other programming languages are compiled to or interpreted as.
+ Binary numeral system, History: Numbers
  * Binary was invented by many people but the modern binary number system is credited to Gottfried Leibniz in 1679, a German mathematician. Machine code is binary digits.

Binary hydride
* Hydride binary compound
* Hydrides are alloys containing nickel, rare-earth metals, aluminum and manganese
  - react with water, so there are no hydrides found in nature

### binary hydride:

Metal hydride
* Some metal hydrides can store even more volume than liquid hydrogen.
* are a safe mobile storage method
  - heavy, expensive, and release heat during the hydrogen absorption process
  - intermetallic alloys that, when cooled, absorb hydrogen gas into a solid form
* provide a means for safe, high-volume density hydrogen energy storage.

Binary sodium chloride
* Most sodium chloride conducts electricity.
* Sodium chloride binary compound
* Sodium chloride can cause eye and skin irritation if used in too high concentrations
  - partially dry an organic phase when used as a concentrated brine wash
  - comes from underground deposits sea water, brine
  - cube
  - does precisely nothing to pH and hardness
* Sodium chloride is added to the ice to lower the freezing point of the ice
  - also very soluble
  - always sodium chloride
  - an electrolyte
* Sodium chloride is an example of a crystalline solid
  - a strong electrolyte
  - an antacid
  - an ionic crystal
  - ideal encapsulation material
* Sodium chloride is an ionic compound, that is the components are present as ions
  - basic table salt
  - by far the most common salt that exists naturally on the Earth
  - called an ionic compound
  - chemical compounds
* Sodium chloride is common salt
  - table salt which is important in animal nutrition
  - commonly deficient in swine rations
  - formed by the combination of sodium and chlorine
  - important for animal nutrition
  - inorganic compounds
  - mined in a similar manner
  - nutrients
  - odorless but has a characteristic taste
  - only one of more than six million known compounds
  - relatively inexpensive, but it can burn plants and corrode metal and concrete
  - soluble in water and very slightly soluble in ethanol
* Sodium chloride is the chemical name for common table salt
  - most common chlorine ore
  - salt most commonly used to season food
  - same in the U.S. as it is in China
* Sodium chloride is used because it is cheap and easy to obtain in large quantities
  - for three reasons
  - in veterinary medicine as emesis causing agent
  - relatively inexpensive salt compared to calcium chloride
  - synthetic form of salt - table salt
* Some sodium chloride exists as crystal.
+ Chemistry, Concepts of chemistry, Acids and bases
  * Acids and bases are common chemicals. Acids can react with bases. A salt is also made when an acid and a base react together. Sodium chloride is a salt.
+ Chlorine, Occurrence: Chemical elements :: Halogens
  * Chlorine is not found as an element. Sodium chloride is the most common chlorine ore. There are some organic compounds that have chlorine in them, too.
+ Crystal structure: Chemistry :: Minerals
  * The 'crystal structure' of a chemical is the shape of the crystal. There are several shapes of crystals. Sodium chloride is a cube. Copper sulfate is triclinic. Most things, even metals, have crystal structures. Some crystals fit more atoms in them than others. These crystals weigh more.
