subscripts define the ratio of atoms to atoms, or ions to ions in a compound. they are set by the valence electrons, they only fit in certain ways.
why change them other than to make balancing equations easier.
balancing equations is not supposed to be too easy, just work harder at it.
don't adjust the universe to fit into a simple way to look at things.

∙ 12y agoThe subscripts tell how many atoms of each element make up a molecule or ionic compound. The law of definite proportions states that a chemical compound always contains exactly the same proportion of elements by mass. Because of this, you cannot change the formulas of the reactants and products in an equation. You can only change the quantity by using coefficients.

What cant be changed when balancing a chemical equation?
when balancing a chemical equation you can not change the subsripts- the small numbers after the element-.
How do you write iron plus sulfur?
SFe, but the thing is that you still need to subscripts so i cant help you there
Is it a chemical change when soot is produced and deposited on a metal?
Producing soot by burning something is a chemical change, but when it is deposited on metal (or anything else), that is a not a chemical change.See the Related Questions to the left for more information.
Why cant a mixture have a unique chemical formula?
Because in a mixture, there are no bonds formed between the elements, and therefore the proportions of each element are unknown, for the mixture as a whole. A mixture is not a chemical change.
Are rotten leaves a physical or chemical change?
Both, but chemical dominates.
Why can't you balance an equation by changing the subscripts of the reactants or the products?
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.Source: (e2020)

Why can't subscripts be changed?
Because if you change a subscript, you change the compound. H2O is water. H2O2 is hydrogen peroxide. They are not the same thing. I assume you are balancing equations. Change the coefficients but then you are only changing the number of molecules of said compound and not the compound itsel.
Why cant an unbalanced chemical equation fully describe a reaction?
The amounts of reactants and products are not mentioned.
Does a physical or a chemical change?
A phsical change is something that can be changed but cant be changed back. for example: you can crumple a piece of paper but it is still paper. A chemical change means it has been changed perminetly so for example: If you burn the paper its ashes not paper. it was ashes but youy cant change it back into paper. Hope this helps :)
Why cant you change the charge of an ion to make formulas?
You can't change the charge because that is changing the very chemical nature of the ion/atom. To make formulas with ions, you use subscripts to change the NUMBER of ions in the formula without changing the CHARGE.
How do you write iron plus sulfur?
SFe, but the thing is that you still need to subscripts so i cant help you there
Is baked bread a chemical change?
Yes it is because the chemical properties change and it cannot be reversed.
Why cant a chemical reaction be put back the same?
cause chemical reactions cant be reversed

Why mole concept is used in balancing chemical equation?
mole concept is used in balancing chemical reaction because for balancing a reaction u cant change the numbers such as 1,2,3 etc.. in between the compund so as a whole we are changing outside the compound
Why cant i just write the down all the answer to aliner equation?
Because there is no such thing as "aliner" equation.
