  2. Salt metathesis reaction - Wikipedia

    en.wikipedia.org/wiki/Salt_metathesis_reaction

    A neutralization reaction is a type of double replacement reaction. A neutralization reaction occurs when an acid reacts with an equal amount of a base. This reaction usually produces a salt. One example, hydrochloric acid reacts with disodium iron tetracarbonyl to produce the iron dihydride: 2 HCl + Na 2 Fe(CO) 4 → 2 NaCl + H 2 Fe(CO) 4

  3. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    Another example of a double displacement reaction is the reaction of lead(II) nitrate with potassium iodide to form lead(II) iodide and potassium nitrate: + + Forward and backward reactions According to Le Chatelier's Principle , reactions may proceed in the forward or reverse direction until they end or reach equilibrium .

  4. Dwell mechanism - Wikipedia

    en.wikipedia.org/wiki/Dwell_mechanism

    A double dwell cam mechanism has a motion function which follows a rise-dwell-fall-dwell motion function sequence that repeats.. Unlike the single dwell, the rise function position ends with the follower's acceleration becoming zero, as it is stationary in the first dwell.

  5. Random walk - Wikipedia

    en.wikipedia.org/wiki/Random_walk

    An elementary example of a random walk is the random walk on the integer number line which starts at 0, and at each step moves +1 or −1 with equal probability. Other examples include the path traced by a molecule as it travels in a liquid or a gas (see Brownian motion ), the search path of a foraging animal, or the price of a fluctuating ...

  6. Castigliano's method - Wikipedia

    en.wikipedia.org/wiki/Castigliano's_method

    Castigliano's method for calculating displacements is an application of his second theorem, which states: If the strain energy of a linearly elastic structure can be expressed as a function of generalised force Q i then the partial derivative of the strain energy with respect to generalised force gives the generalised displacement q i in the direction of Q i.

  7. Buckley–Leverett equation - Wikipedia

    en.wikipedia.org/wiki/Buckley–Leverett_equation

    In fluid dynamics, the Buckley–Leverett equation is a conservation equation used to model two-phase flow in porous media. [1] The Buckley–Leverett equation or the Buckley–Leverett displacement describes an immiscible displacement process, such as the displacement of oil by water, in a one-dimensional or quasi-one-dimensional reservoir.

  8. SN2 reaction - Wikipedia

    en.wikipedia.org/wiki/SN2_reaction

    For example, the synthesis of macrocidin A, a fungal metabolite, involves an intramolecular ring closing step via an S N 2 reaction with a phenoxide group as the nucleophile and a halide as the leaving group, forming an ether. [2] Reactions such as this, with an alkoxide as the nucleophile, are known as the Williamson ether synthesis.

  9. Dual process theory - Wikipedia

    en.wikipedia.org/wiki/Dual_process_theory

    According to Alos-Ferrer and Strack the dual-process theory has relevance in economic decision-making through the multiple-selves model, in which one person's self-concept is composed of multiple selves depending on the context. An example of this is someone who as a student is hard working and intelligent, but as a sibling is caring and ...
