A standard value or a constant can be established in an experiment by using a control group
In fact, the control group is used to observe the result under normal conditions or standard conditions in order to obtain a constant value which at the same time is used to compare the outcomes from the experimental groups

7 (a)* The Planck constant h can be measured in an experiment using light-emitting diodes LEDs) Each LED used in the experiment emits monochromatic light. Te wavelength λ of the emitted photons is detemined during the manufacturing process and is provided by the manufacturer When the p.d. across the LED reaches a specific minimum value suddenly switches on emitting photons of light of wavelength the LED andi are related by the energy equation eVi hh flying lead Fig. 7.1 LED...
At equilibrium, the concentrations of reactants and products can be predicted using the equilibrium constant, Kc, which is a mathematical expression based on the chemical equation. For example, in the reaction aA+bB?cC+dD where a, b, c, and d are the stoichiometric coefficients, the equilibrium constant is Kc=[C]c[D]d[A]a[B]b where [A], [B], [C], and [D] are the equilibrium concentrations. If the reaction is not at equilibrium, the quantity can still be calculated, but it is called the reaction quotient, Qc, instead of...

At equilibrium, the concentrations of reactants and products can be predicted using the equilibrium constant, Kc, which is a mathematical expression based on the chemical equation. For example, in the reaction Part A aA + bB = CC + dD A mixture initially contains A, B, and C in the following concentrations: [A] = 0.350 M , [B] = 1.15 M, and [C] = 0.600 M. The following reaction occurs and equilibrium is established: where a, b, c, and d...
