In science, a coefficient typically represents the numerical factor in a chemical equation that indicates the number of moles of a substance involved in a reaction. It helps balance chemical equations by ensuring that the conservation of mass is achieved.
A coefficient in chemistry, as in other disciplines, is a number that comes before or in front of some expression. It could be in front of an element, a compound, etc. and indicates the number of atoms, molecules, moles, etc. of that expression. An example might be the following: 4 Al + 3 O2 -->2 Al2O3.In this example, the coefficients are 4, 3 and 2 indicating 4 moles Al, 3 moles O2 and 2 moles Al2O3, respectively.
Coefficients are, in general, a number that is a factor of a term in a formula. It is constant, and so doesn't contain any of the variables of the formula. For example for a fixed resistor with 5 ohms, the voltage V= 5I (I=current) the number 5 is a coefficient. Other formulae have other coefficients, and particular measurements may be named coefficients. Eg the coefficient of friction. tl;dr They are numbers, different coefficients tell you different things
The coefficient for Cl₂ is 1. If not written explicitly in a chemical equation, a coefficient of 1 is understood to be present.
The coefficient for H2O in an equation represents the number of water molecules. In this case, the coefficient for 4H2O would mean there are 4 water molecules present.
The material with the highest coefficient of thermal expansion is typically graphite.
When using scientific notation the coefficient does not have to be less than any number or value from physical science.
The term coefficient refers to a number that is next to a variable. For example in the term 4x2, 4 is a coefficient, and 2 is an exponent; x is a variable.

The Mr. Science Show was created in 1991.
The Mr. Science Show ended in 1995.
A coefficient in science is a constant obtained from experimentation and/or observation by which a variable is multiplied in measuring a change in some property of a system under determined conditions. For example, in the formula:I = Emix (σ) (T)^4 / πThe coefficients are Emix , σ and π. These coefficients don't change.

a coefficent in physical science means:a number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product that are involved in a reaction
Its the number before a letter that is being multiplied.. so for example 2X.. 2 would be the coefficient.
negative tempareture It depends on the reverse voltage. Up to about 5.6 volts, the zener has a negative temperature coefficient. Beyond 5.6 volts it begins to show a positive temperature coefficient.
Strength coefficient is a parameter used in materials science to quantify the relationship between stress and strain in a material. It represents the ability of a material to withstand deformation before reaching its breaking point. The higher the strength coefficient, the stronger the material is under load.
