What else can I help you with?
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The formula would no longer represent the same substance.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.
Are the number of atoms in a compound determined by miltiplying the subscripts by the coefficiants?
No, the number of atoms in a compound is determined by the subscripts alone, which indicate the number of each type of atom in a single molecule of the compound. Coefficients, placed in front of a chemical formula, indicate the number of molecules or formula units of the compound present. To find the total number of atoms in a reaction, you would multiply the subscripts by the coefficients for each molecule involved.
Is it true that subscripts can be changed in order to balance a chemical equation?
No, subscripts cannot be changed in a chemical formula to balance a chemical equation. Balancing a chemical equation involves adjusting the coefficients in front of the chemical formulas to ensure that the number of each type of atom is the same on both sides of the equation. Changing subscripts would alter the chemical identities of the substances involved.
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 is the definition on a combination of symbols that show ratio of elements in a compound?
A chemical formula is a combination of symbols that shows the ratio of elements in a compound. Each element is represented by its chemical symbol, and the subscripts indicate the relative number of atoms of each element in the compound.
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 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The formula would no longer represent the same substance.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 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.
Why is it important to never change the subscript in a chemical formula when balancing a chemical equation?
It is important to never change the subscript in a chemical formula when balancing a chemical equation because subscripts represent the number of atoms of each element in the compound. Changing subscripts would alter the chemical formula and consequently change the identity of the compounds involved in the reaction. Balancing equations involves adjusting coefficients, not subscripts.

What Never change a subscript to balance an equation?
Subscripts in a chemical formula represent the number of each atom present in a compound. Changing a subscript without changing the corresponding coefficients in a balanced chemical equation would alter the chemical formula and lead to an unbalanced equation. To balance the equation, adjust the coefficients in front of the compounds rather than changing the subscripts.
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.

What would be the empirical formula for glucose C6H12O6?
The empirical formula of glucose is the formula which has the lowest ratio. You can divide all three elements by 6 to give: CH2O.

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.
