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.

What doese a coefficient tell you?
In chemistry, a coefficient in front of a chemical formula tells you how many moles you have. When balancing a chemical equation, the law of conservation of matter must be upheld. To do this, you add coefficients as needed, and these coefficients represent mole ratios of either reactants or products.
What is the coefficent?
The coefficient is the number that goes before the variable. In mathematics, this variable can be x, y, or any other letter. In chemistry, this variable is seen as the element name (e.g. Ca, Br, Cl). In chemistry, variables are used to balance out chemical equations.
The number placed in front of a chemical symbol or formula is called?
Coefficient
Affect of pH in partition coefficient?
effect of stomach PH on partition coefficient
What represents the number of units of each substance taking part in a reaction?
synthesis
The number of oxygen atoms in 6CH3COOH?
The formula without the coefficient has 2 oxygens, but multiply that by the coefficient of 6 gets you 12 oxygens. In chemistry, a coefficient in front of a compound applies to everything in that compound even though there aren't any parentheses.
What has the author J Sangster written?
J. Sangster has written: 'Octanol-water partition coefficients' -- subject(s): Water, Octyl alcohol, Partition coefficient (Chemistry)
What s a number that is multiplied by a variable?
A coefficient, possibly.A coefficient, possibly.A coefficient, possibly.A coefficient, possibly.
What is the number factor of a variable called?
The coefficient is in front of a variable.
How is coefficient of determination and coefficient of correlation is related?
coefficient of determination
Why is it important to reduce coefficient in a balanced equation to the lowest possible whole number?
It is not always important. In chemistry, for example, you would never reduce C2H2 (acytelene) and C6H6 (benzene) to CH.
Application of Solutions in the body chemistry?
The solution chemistry is a most significant science of mixtures which develop new physicochemical properties such as surface tension, interfacial tension, wetting coefficient, tentropy, IMMFT, friccohesity and vicosity. The properties decide the fate and utility of the resultant liquid mixtures. In this context, the survismeter is a best tool for solution chemistry for measuring the abovementioned data.
Example of coefficient?

What is an austausch coefficient?
An austausch coefficient is a coefficient of turbulent flow in eddies.
What is the literal coefficient of 5x?
x the literal coefficient is the letter tagging along with the number coefficient (the number coefficient is 5, here). number coefficient is also sometimes called leading coefficient. literal coefficient is the variable (which is always a letter: English or latin).
Differentiate numeral coefficient from literal coefficient?
numeral coefficient or numerical coefficient is a number used in an algebraic term, while literal coefficient is the letter used to represent a number.
What is an literal coefficient?
Literal coefficient is the number followed in a numerical coefficient.example: 3x - 3 is the numerical coefficient and x is the literal coefficient.=)
