When balancing a chemical equation, you must never change the chemical formulas of the substances involved. You can only adjust the coefficients in front of the compounds to ensure the number of each type of atom is the same on both the reactant and product sides.

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.
Why is it important never to change a subscription in a chemical formula when balancing a chemical equation?
Changing the subscription in a chemical formula alters the identity of the compound, resulting in an inaccurate representation of the reactants and products in a chemical equation. Balancing chemical equations requires maintaining the same elements in the same proportions on both sides of the equation to satisfy the law of conservation of mass. Changing a subscript would violate this principle and lead to an incorrect balance.
What can never be changed when balancing an equation?
The number and type of atoms must always remain the same on both sides of the equation when balancing a chemical equation. This requirement is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
What do you add when balancing a chemical equation?
Coefficients to the chemical formulas to ensure that the number of atoms for each element is the same on both sides of the equation.
What scientific law requires that subscripts in formulas should never be changed while balancing a chemical equation?
The law of conservation of mass requires that subscripts in chemical formulas remain unchanged while balancing a chemical equation. This law states that mass is neither created nor destroyed in a chemical reaction, so the number and type of atoms on each side of the equation must be equal. Changing subscripts would alter the formula and violate this principle.

When balancing a chemical equation can you adjust the script in a formula?
When balancing a chemical equation, you can adjust the coefficients (numbers in front of the elements or compounds) to balance the number of atoms on each side of the equation. You cannot change the subscripts within a chemical formula as this would change the identity of the compound. The only modifications allowed are changing the coefficients to achieve balance.
What do you add when balancing a chemical equation?
Coefficients to the chemical formulas to ensure that the number of atoms for each element is the same on both sides of the equation.
What has to happen for a chemical equation to be balanced?
To balance a chemical equation, the number of atoms of each element in the reactants must be equal to the number of atoms of the same element in the products. This is done by adjusting the coefficients of the reactants and products while keeping the chemical formulae unchanged.
When balancing a chemical equation do you alter the coefficients but not the subscripts in the equation?
Yes, when balancing a chemical equation, you only change the coefficients in front of the chemical formulas to balance the number of atoms on both sides of the equation. Subscripts, which represent the number of atoms within a molecule, remain unchanged as they reflect the actual chemical formula of the compound.

Changing subscripts would alter the formula and violate this principle.
Should you never change a subscript to balance an equation?
No, it is not recommended to change subscripts in a chemical formula to balance an equation. Subscripts represent the number of atoms of each element in a compound and altering them would change the compound itself, resulting in an incorrect chemical equation. Balancing equations should be done by adjusting coefficients in front of the chemical formulas.
Why do you never use fractions when balancing an equation?
It is customary to use integers.
What can NEVER change these to make the equation balanced?
Changing subscripts in chemical formulas should never be done to balance a chemical equation because it changes the identity of the compounds involved. Instead, coefficients should be adjusted to balance the equation without altering the chemical formulas.
A chemical reaction is balanced by changing?
A chemical reaction is balanced by changing the coefficients of the reactants and products in the equation. The aim is to ensure that the number of atoms of each element is the same on both sides of the equation. This balancing process is necessary to follow the law of conservation of mass.
