You can't change the subscript. The subscripts show how the elements/molecules are bonded.
--------------------------------------------------------------------------------------------------------
The subscripts represent the number of atoms of each element in each chemical formula-if you change the subscripts, you change the compounds the formulas are describing.

Because the subscripts in a chemical equation represent the numbers of atoms present in specific compounds or elements that are the reactants or products. Changing the subscripts would cause the formulas to represent a different compound or molecule, or more likely something that doesn't exist at all. Instead of changing the subscripts, the coefficients that are written before the formulas must be changed.
For example, if you were balancing an equation involving Carbon Dioxide:
CO2
And you wanted one less Oxygen atom on one side of the reaction you could not do this by adjusting the 2 subscript in Carbon Dioxide because that would make it Carbon Monoxide:
CO
In the reaction below [which is not balanced]
C6H6 + O2 -> CO2 + H2
You could not write:
C6H6 + 3O2 -> 6CO + 3H2
because Carbon Monoxide is not produced in the reaction.
Its just like trying to change an exponent in math. you just cant. Instead you change the coefficents in front of the atoms. and if you have a 2 subscript and a 3. make them both 6 by putting a 3 and 2 in front of them
The subscripts are part of the unique identity of the chemical formula of a molecule or compound. If you change the subscripts, it is no longer that substance, and the equation will be incorrect. You can only change the amounts of molecules or compounds by changing the coefficients in front of the chemical formulas when balancing an equation.
Because changing the subscript changes the chemical makeup of the molecule itself. Balancing involves changing the coefficients found before the molecule
The subscripts of the reactants and products define the chemical compounds that are involved. You must change the quantitys of the compounds in the equation.
If you change the subscripts in a chemical formula, it will no longer represent the same substance. You can only add coefficients to balance a chemical equation.
Tsubscripts of the reactants equal the subscripts of the products.
The subscripts determine what the chemicals are, you have to change the amount of the reactants/products rather than change what the reactants/products actually are eg O2 is oxygen gas, if you wanted 4 of them to balance it it would have to be 2 O2 otherwise it wouldn't be oxygen gas any more.
reactants ---> products
reactants -----> products is correct
No. The reactants are written on the left of the arrow.
false
Tsubscripts of the reactants equal the subscripts of the products.
false
When you are balancing known reactants and known products which is always the case when you are asked to "balance" a chemical equation you must not change the subscripts as that changes the reactants or the products to a different chemical compound.

Chemical reaction is the making and breaking of chemical bonds, leading to changes in the composition of matter. Chemical reactions do not create or destroy matter; they only rearrange it in various ways.
relative amounts of reactants and products
reactants -----> products is correct
A skeleton equation in chemistry contains obviously the abbreviations of the elements you are being asked to represent. it may contain the exponents also known as subscripts but it does not include coefficients.
No. The reactants are written on the left of the arrow.
These are reactants and products.
