In chemistry, there are seven "strong" acids. What makes them "strong" is the fact that they completely dissociate into their ions (H+and an anion) when they are mixed with water. Every other acid is a weak acid. Because there are only seven common strong acids, it is easy to commit...
Implicit models for evaluation of electrostatic energies in proteins include dielectric constants that represent effect of the protein environment. Unfortunately, the results obtained by such models are very sensitive to the value used for the dielectric constant. Furthermore, the factors that determine ...
What units are typically used to express the rate of a reaction? In the reaction A + B ---> C explain at least two ways in which the rate law could be zero order in chemical A. What is the relationship between K and the rate constants? The rate constant of a certain reaction is ...
What are the constants in Charles' law?Question:What are the constants in Charles' law?Constants:In science, there are often values that need to be included in equations to make them produce the correct answers. These values are called constants and when using the ideal gas law each different...

Unfortunately, the results obtained by such models are very sensitive to the value used for the dielectric constant. Furthermore, the ...
Equilibrium constants (K, Kc, Kp) should not have units for many reasons. 1. Activities should be used not concentrations as activities are more accurate for real solutions and real gasses. Activities do not have units. What is QC in chemistry? The reaction quotient Q is a measure of the...
Experimental data enables the calculation of accurate rate constants and activation energies for use in models. For very fast reactions, or for reactions that at times exhibit periods of rapid change in composition, more data points are required than offline methods can provide. Real-time, in-...
Equation of motion coupled-cluster calculations (EOM-CCSD) have been performed to obtain 15N−15N and 17O−17O coupling constants (2hJX-X) across N−H+−N and O−H+−O hydrogen bonds in a series of protonated dimers. 2hJX-X values are dominated by the Fermi-contact term and...
Variables in Science: A Deep Dive By Anne Marie Helmenstine, Ph.D. Physical constantsare quantities which you cannot change. They may be calculated or defined. Examples: Avogadro's number, pi, the speed of light, Planck's constant
Inductance is defined as the property of an electric conductor which causes an electromotive force that is generated due to a change in the current flow. There are two types of inductance: self-inductance and mutual inductance.
