The formula would no longer represent the same substance.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.
No - they are usually balanced by changing the numbers before the molecules.
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.
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.
The formula unit AlN represents aluminum nitride. The formula indicates that there is one aluminum atom (Al) for every one nitrogen atom (N), so no subscripts are needed to balance the formula unit.
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.
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.
Do you mean subscripts like H2O (ie the 2 would be subscripted)?
Changing subscripts in a chemical formula changes the actual chemical species present, leading to a different reaction. Subscripts represent the ratio of elements in a compound and should not be changed to balance chemical equations. Balancing equations is done by adjusting coefficients in front of chemical formulas, not by changing subscripts.
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.
Changing subscripts in a chemical formula changes the identity of the compound being represented. Balancing a chemical equation involves changing the coefficients in front of the chemical formulas to ensure that the same number of each type of atom is present on both sides of the equation.
No - they are usually balanced by changing the numbers before the molecules.
Balancing only allows you to change the coefficients, NOT the subscripts.
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.
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.
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.
No subscripts are needed: The formula unit for calcium oxide contains one calcium cation with a charge of +2 and one oxide anion with a charge of -2.
Changing subscripts changes the chemical formula, leading to a different compound being represented. When balancing a chemical equation, you can only add coefficients to the compounds to ensure mass is conserved on both sides of the equation while keeping their identities the same. Changing subscripts would alter the chemical substances involved in the reaction.
