when you put is as a subscript such as CO2 you are showing that there are two atoms of oxygen in the molecule of carbon dioxide.

When you put the two at the beginning of the phrase such as 2CO you are showing that you have two separated molecules of carbon linked to oxygen.

What is the difference between a subscript and a coefficient in a chemical formula?

The subscripts tell you how the atoms are bound together. The coefficient tells you how many atoms there are.


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.


Why is Fe balanced with coefficient of 3 instead of a subscript of 3?

The subscript is mentioned only in a chemical formula.3 FeCl3 in a chemical reaction is not similar to Fe3O4 in a chemical formula.


How does a subscript in a chemical formula affect balancing chemical equation?

When balancing a chemical equation, you multiply the subscripts in a chemical formula times the coefficient in front of the formula to get the total number of atoms of each element.


What is the number placed in front of a chemical formula that tells how many atoms or molecules there are in the formula?

That is called a coefficient in a chemical equation. It indicates the number of molecules or units of a substance involved in a reaction.


What is the difference between a coefficient number and subscript number?

A coefficient number indicates how many units of a molecule or compound are involved in a chemical reaction, often found in front of a chemical formula (e.g., 2 in 2H₂O). In contrast, a subscript number appears within a chemical formula and specifies the number of atoms of an element in a molecule (e.g., the 2 in H₂O indicates there are two hydrogen atoms). Thus, coefficients relate to the quantity of entire compounds, while subscripts relate to the composition of individual molecules.


Why is the number placed below an element symbol in a chemical formula is called a subscript?

The number placed below an element symbol in a chemical formula is called a subscript because it indicates the number of atoms of that element in a molecule or compound. The subscript is written slightly below the element symbol to differentiate it from the coefficient, which applies to the whole molecule or compound.


What do the subscript and coefficent in a chemical equation tell us?

The subscript in a chemical equation tells us the ratio of atoms of each element present in a compound. The coefficient tells us the number of molecules or formula units involved in the reaction.


What does a subscript in a chemical formula represents?

The subscript in a chemical formula represents the amount of that atom in that compound's formula.


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

How many oxygen atom does this have 12N2O5?

The answer to such questions is always the product of the coefficient number before the formula and the subscript number after the atom specified, in this instance 12 X 5 = 60.
