  2. Limiting reagent - Wikipedia

    en.wikipedia.org/wiki/Limiting_reagent

    This method is most useful when there are only two reactants. One reactant (A) is chosen, and the balanced chemical equation is used to determine the amount of the other reactant (B) necessary to react with A. If the amount of B actually present exceeds the amount required, then B is in excess and A is the limiting reagent.

  3. AIM-120 AMRAAM - Wikipedia

    en.wikipedia.org/wiki/AIM-120_AMRAAM

    The AIM-120 [a] Advanced Medium-Range Air-to-Air Missile (AMRAAM) (/ æ m r æ m / AM-ram) is an American beyond-visual-range air-to-air missile capable of all-weather day-and-night operations. It uses active transmit-receive radar guidance instead of semi-active receive-only radar guidance.

  4. Quantities, Units and Symbols in Physical Chemistry

    en.wikipedia.org/wiki/Quantities,_Units_and...

    Quantities, Units and Symbols in Physical Chemistry, also known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants , tables listing the properties of elementary particles , chemical elements , and nuclides , and information about conversion ...

  5. Lists of physics equations - Wikipedia

    en.wikipedia.org/wiki/Lists_of_physics_equations

    In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.

  6. Calibration curve - Wikipedia

    en.wikipedia.org/wiki/Calibration_curve

    A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

  7. Free recoil - Wikipedia

    en.wikipedia.org/wiki/Free_recoil

    Free recoil / Frecoil is a vernacular term or jargon for recoil energy of a firearm not supported from behind. Free recoil denotes the translational kinetic energy (E t) imparted to the shooter of a small arm when discharged and is expressed in joules (J), or foot-pound force (ft·lb f) for non-SI units of measure.

  8. Ballistic coefficient - Wikipedia

    en.wikipedia.org/wiki/Ballistic_coefficient

    When the correct G model retardation factors are applied within the Siacci mathematical formula for the same G model C b, a corrected trajectory can be calculated for any G model. Another method of determining trajectory and ballistic coefficient was developed and published by Wallace H. Coxe and Edgar Beugless of DuPont in 1936.

  9. Gibbs free energy - Wikipedia

    en.wikipedia.org/wiki/Gibbs_free_energy

    Its symbol is Δ f G˚. All elements in their standard states (diatomic oxygen gas, graphite, etc.) have standard Gibbs free energy change of formation equal to zero, as there is no change involved. Δ f G = Δ f G˚ + RT ln Q f, where Q f is the reaction quotient. At equilibrium, Δ f G = 0, and Q f = K, so the equation becomes Δ f G˚ = − ...
