What would changing the subscripts do to the formula?
The formula would no longer represent the same substance.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 do you write to name of a compound written as Cu0?
This is the formula for Copper (II) Oxide Copper has two possible oxidation numbers (+2 or +1) since there are no written subscripts for in the formula CuO, copper's oxidation number must have been +2 (If it had been +1, the formula would be Cu2O and the name of the compound woould be Copper (I) Oxide)
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)
What is the chemical symbol or formula for the form of copper that is present after adding nitric acid to copper?
balanced formula: 2 HNO3 + Cu = Cu(NO3)2 + H2more specifically, the copper product would be Cu(NO3)2note: #'s are supposed to be subscripts
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 to use subscripts when writing a formula?
Do you mean subscripts like H2O (ie the 2 would be subscripted)?
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.
What is the empirical formula C12H6O3?
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, since 15/3 = 5, a prime number, and 5 is not an integral factor of 9 or 3. Therefore, the empirical formula would be C3H5O.
What is the empirical formula for C2H6O?
CH3O: When a molecular formula has a set of subscripts that can all be integrally divided by any integer other than one, division of the subscripts by the highest such integer will yield the empirical formula.

Can subscripts in a chemical formula be fractions?
The Subscripts in a Chemical formula explain how the atoms in that compound are chemically bonded. As a fraction of an atom cannot bond, the subscripts cannot be fractions. Coefficients, however which go before a chemical formula in chemical equations may be fractions. This is because they explain the ratio of the number of moles of each species required for the reaction and it is possible to have a fraction of a mole of something.

Is CaMgCO a element or a compound?
It would be a compound. An element's symbol never has more than three letters and never has more than one uppercase letter. Note, though that no compound with this formula exists. You must remember your subscripts. The correct formula is CaMg(CO3)2, the formula for the mineral dolomite.

What is the chemical formula for copper (I) carbonate?
Copper carbonate is CuCO3 (copper(II) carbonate)
