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.
The subscripts tell you how the atoms are bound together. The coefficient tells you how many atoms there are.
it's a subscript
How does a subscript affect the element just before it?
d
The coefficient (not a subscript or superscript) placed immediately before the formula of the reactant in the equation shows how many moles of a reactant are involved in the reaction. If there is no explicit coefficient, a value of 1 for the coefficient is assumed. The coefficient in front of the molecule tells its relative number of moles.
The subscripts tell you how the atoms are bound together. The coefficient tells you how many atoms there are.
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.
The subscript is mentioned only in a chemical formula.3 FeCl3 in a chemical reaction is not similar to Fe3O4 in a chemical formula.
it's a subscript
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 does a subscript affect the element just before it?
In chemical formulas, a subscript number signifies the number of atoms of the specified element in a molecule. For example, H2O (where the "2" is subscript) is the formula for water and represents 2 hydrogen atoms combined with 1 atom of oxygen.
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
The subscript in a chemical formula refers to the _____.
atomic number or atomic weight. Subscript: atomic number, superscript: atomic weight: 94Pu239 or 239Pu
d
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.
