The formula would no longer represent the same substance.
CO is carbon monoxide a poisonous gas.
CO2 is carbon dioxide, a nonpoisonous gas.
H2O is water -- you can drink it
H2O2 is hydrogen peroxide. Don't drink it.

What subscripts would properly complete the formula unit Al N?
1,3
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.
When balancing a chemical equation can you adjust the script in a formula?
No. Never change the subscripts because then you are changing the formula of the substance to something else. You can only change the amount of a substance by adding a coefficient in front of the formula. If there is no coefficient, it is understood to be 1.
Why are subscripts in a chemical formula whole numbers?
o
Are chemical equations balanced by changing the subscripts of the molecules?
No - they are usually balanced by changing the numbers before the molecules.
When to use subscripts when writing a formula?
Do you mean subscripts like H2O (ie the 2 would be subscripted)?
What subscripts would properly complete the formula unit Al N?
1,3
How can you balance a chemical equation by changing the subscripts?
Balancing only allows you to change the coefficients, NOT the subscripts.

What is the empirical formula for C9H15O3?
A molecular formula is identical to the empirical formula. The principle for this kind of problem is to find the highest integer that is an integral factor of all the subscripts then divide the subscripts by that integer. In this instance 3 is the highest integer. Therefore the empirical formula would be C3H5O.
Describe the meaning of the subscripts in the formula for glucose C6H12O6?
The meaning of subscripts in a chemical formula is to indicate the number of a given atom in the molecule.
In a chemical formula what do subscripts mean?
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
When balancing a chemical equation can you adjust the script in a formula?
No. Never change the subscripts because then you are changing the formula of the substance to something else. You can only change the amount of a substance by adding a coefficient in front of the formula. If there is no coefficient, it is understood to be 1.
What does it mean when there are no subscripts in a formula?
No subscripts mean only one atom in formula. Example: KCl - 1 atom of potassium, 1 atom of chlorine.
Why are subscripts in a chemical formula whole numbers?

Explain specifically what the subscripts mean in the molecule formula C6H12O6?
explain specifically what the subscripts mean in the molecule formula c 6 h 12 o 6
Are chemical equations balanced by changing the subscripts of the molecules?
No - they are usually balanced by changing the numbers before the molecules.
