  2. Mass balance - Wikipedia

    en.wikipedia.org/wiki/Mass_balance

    The general form quoted for a mass balance is The mass that enters a system must, by conservation of mass, either leave the system or accumulate within the system. Mathematically the mass balance for a system without a chemical reaction is as follows: [2]: 59–62

  3. Analytical balance - Wikipedia

    en.wikipedia.org/wiki/Analytical_balance

    An analytical balance (or chemical balance) is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg resolution or better) is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation ...

  4. Conservation of mass - Wikipedia

    en.wikipedia.org/wiki/Conservation_of_mass

    In chemistry, the calculation of the amount of reactant and products in a chemical reaction, or stoichiometry, is founded on the principle of conservation of mass. The principle implies that during a chemical reaction the total mass of the reactants is equal to the total mass of the products. For example, in the following reaction

  5. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    Mole to mass: Convert moles of Ag to grams of Ag produced; The complete balanced equation would be: Cu + 2 AgNO 3 → Cu(NO 3) 2 + 2 Ag. For the mass to mole step, the mass of copper (16.00 g) would be converted to moles of copper by dividing the mass of copper by its molar mass: 63.55 g/mol.

  6. List of chemical process simulators - Wikipedia

    This is a list of software used to simulate the material and energy balances of chemical process plants. Applications for this include design studies, engineering studies, design audits, debottlenecking studies, control system check-out, process simulation, dynamic simulation, operator training simulators, pipeline management systems, production management systems, digital twins.

  7. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. [1] ... Mass balance; Microscopic reversibility;

  8. Plug flow reactor model - Wikipedia

    en.wikipedia.org/wiki/Plug_flow_reactor_model

    A material balance on the differential volume of a fluid element, or plug, on species i of axial length dx between x and x + dx gives: [accumulation] = [in] - [out] + [generation] - [consumption] Accumulation is 0 under steady state; therefore, the above mass balance can be re-written as follows: 1.

  9. Modeling and simulation of batch distillation unit - Wikipedia

    en.wikipedia.org/wiki/Modeling_and_simulation_of...

    The following differential mass balance equation may be written as:Let L be the moles of material in the still and x be the concentration of the volatile component (i.e. A) and let the moles of accumulated condensate be D. Concentration of the equilibrium vapour is Over a small time, the change in the amount of liquid in the still is d L ...
