Bonding energy equation

What is bond energy in chemistry? In chemistry, bond energy (BE), also called the mean bond enthalpy or average bond enthalpy is the measure of bond strength in a chemical bond. The larger the average bond energy, per electron-pair bond, of a molecule, the more stable and lower-energy the molecule. What are the units of […]

Characteristic equation complex roots

What are roots of characteristic equations? discussed in more detail at Linear difference equation#Solution of homogeneous case. The characteristic roots (roots of the characteristic equation) also provide qualitative information about the behavior of the variable whose evolution is described by the dynamic equation. How do I know if my roots are complex? When graphing, if […]

Free fall time equation

What is the formula for time in free fall? Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling. Velocity is defined as […]

Foci equation

How do you find foci? actually an ellipse is determine by its foci. But if you want to determine the foci you can use the lengths of the major and minor axes to find its coordinates. Lets call half the length of the major axis a and of the minor axis b. Then the distance […]

Steady state concentration equation

What is the steady state concentration? Steady-state concentration (Css) occurs when the amount of a drug being absorbed is the same amount that’s being cleared from the body when the drug is given continuously or repeatedly. Steady-state concentration is the time during which the concentration of the drug in the body stays consistent. How long […]
