A coefficient in a chemical formula tells you how many molecules there are. For example, 3Co2. The number 3 which comes before the C tells you that there are 3 molecules. The coefficient is the first number. This molecules consist of 3 C atoms (1 multiplied by the coefficient 3), and 6 O atoms( 2 multiplied by the coefficient 3)
Another example:
H= one hydrogen atom
H2= one molecule made of 2 hydrogen atoms bonded together
3H20= three molecules consisting of two hydrogen atoms bonded to one oxygen atom

What does a coefficient represent in a chemical formula?
It represents the amount of the substance. It can mean the number of atoms, molecules, formula units, or moles.
What is the number placed in front of a chemical formula that tells how many atoms or molecules there are in the formula?
it's a subscript
What is the coefficient for magnesium chloride and sodium fluoride?
Which coefficient ?The chemical formula of magnesium chloride is MgCl2.The chemical formula of sodium chloride is NaF..
Where does coefficient belong in the chemical formula?
The coefficient in a chemical formula is the large number before each of the reactants or products. In the balanced equation for the synthesis of water: 2 H2 + O2 --> 2 H2O The number 2 in front of the H on both sides of the arrow are the coefficients.
How does a subscript in a chemical formula affect balancing chemical equation?
How does a subscript affect the element just before it?
What is ment by the term coefficient in relation to a chemical reaction?
A coefficient is a number written in front of a chemical formula when balancing a chemical equation. The coefficient can represent the number of atoms, molecules, formula units, or moles of the substance.
The number placed in front of a chemical symbol or formula is called?

A number placed in front of a chemical formula in a chemical equation is called?
In a chemical Equation ,The reactants are on the left side of a chemical equation and the products are on the right side.The number in front of a chemical formula in a chemical equation is called atoms. They should be a balancing number on both the sides.
What is the large number that appears in front of a chemical formula called?
a coefficient
What is a the small whole number that appears in front of a formula in a chemical equation?
It is the coefficient.
What is understood if no coefficient is written before a formula in a chemical equation?
if no number is written following a chemical symbol in a chemical formula, it is understood the number of atoms of that element is one
What is the number in front of a chemical formula called-?
atomic number or atomic weight. Subscript: atomic number, superscript: atomic weight: 94Pu239 or 239Pu

What is the difference between a subscript and coefficiant?
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation.
