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.


What is the number and type of atom in 3 H2O?

In 3 molecules of H2O, which is 3H2O, there are 6 hydrogen atoms and 3 oxygen atoms. You multiply the coefficient of 3 times the subscript of each element. When there is no subscript, it is assumed to be 1.


When FeO4 plus Al Al2O3 plus Fe is balanced what is the coefficient of Fe?

3FeO4 + 8Al --> 3Fe + 4Al2O3


What is the difference between the function of the coefficient and the subscript in a balance equation?

The coefficient is a count of the number of molecules of each substance in a chemical process. The subscript is the number of atoms of an element in each molecule.


What is difference between coefficient and a subscript?

The coefficient applies to all of the elements in the compound whereas the subscript applies to only the select elements; unless the subscript follows parenthesis, in which case it applies to all elements inside. ==========================================================Hope it helped!

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.


What is the total number of oxygen atoms in 5CO2?

10: The total number is the product of the coefficient in front of the chemical formula and the subscript immediately following the symbol of the element asked about. If there is no subscript, a subscript of 1 is inferred.


How many atoms are in 3Fe(OH)3?

What is the differences between subscripts and coefficients?

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.
