The primary difference between a computer algebra system and a traditional calculator is the ability to deal with equations symbolically rather than numerically. The precise uses and capabilities of these systems differ greatly from one system to another, yet their purpose remains the same: manipulation of symbolic equations.
Internal solution, usually a pH=7 buffered solution of 0.1 mol/L KCl for pH electrodes or 0.1 mol/L MCl for pM electrodes. When using the silver chloride electrode, a small amount of AgCl can precipitate inside the glass electrode. Reference electrode, usually the same type as 2. Reference internal solution, usually 3.0 mol/L KCl.

Reaction scheme of the olefin metathesis – changing groups are colored. In organic chemistry, olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds.
The grain per gallon (gpg) is a unit of water hardness defined as 1 grain (64.8 milligrams) of calcium carbonate dissolved in 1 US gallon of water (3.785412 L). It translates into 1 part in about 58,000 parts of water or 17.1 parts per million (ppm). Also called Clark degree (in terms of an imperial gallon).
An increase in this delay can be caused by a pathology, which in turn can result in chaotic solutions for the Mackey–Glass equations, especially Equation . When τ = 6 {\displaystyle \tau =6} , we obtain a very regular periodic solution, which can be seen as characterizing "healthy" behaviour; on the other hand, when τ = 20 {\displaystyle ...
Molybdenum trichloride gives a ether complexes MoCl 3 (thf) 3 and MoCl 3 (Et 2 O) 3.They are beige, paramagnetic solids. Both feature octahedral Mo centers. The diethyl ether complex is synthesized by reducing a Et 2 O solution of MoCl 5 with tin powder. [5]
There are two London equations when expressed in terms of measurable fields: =, =. Here is the (superconducting) current density, E and B are respectively the electric and magnetic fields within the superconductor, is the charge of an electron or proton, is electron mass, and is a phenomenological constant loosely associated with a number density of superconducting carriers.
