Why is it important never to change a subscription in a chemical formula when balancing a chemical equation?
It is important never to change a subscript {note correct spelling} in a chemical formula when balancing a chemical equation, because changing a subscript produces a formula that specifies a chemical substance different from the one in the original equation.
Why does the law of conservation of mass dictate the chemical equation be balanced?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. Therefore, in a balanced chemical equation, the number of atoms of each element must be the same on both sides to ensure that mass is conserved. If the equation is unbalanced, it would imply that mass is not conserved, which goes against this fundamental law of chemistry.
A chemical reaction can be concisely represented by a chemical what?
A chemical reaction can be represented by a chemical equation.
If the mass of all objects before a chemical change is 200kg what would the mass be after the chemical changed occurred?
There will be a gain in mass.....but you can't predict the new change in mass unless you weigh the products after the chemical change occurred.
Is this true or false Subscripts can be changed in order to balance a chemical equation?
True. Subscripts represent the number of atoms of each element in a compound and changing them would change the chemical formula, possibly making it unbalanced in the equation. By adjusting the coefficients of the compounds involved in the reaction, the equation can be balanced without modifying the subscripts.

How does law of the conservation of mass apply to chemical reactions?
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction.
A chemical reaction can be concisely represented by a chemical what?
A chemical reaction can be represented by a chemical equation.
What is a non example of a chemical equation?
I suppose that would be a summary of a change which is not chemical. Perhaps it would be something like ice --> water
Why an unbalanced chemical equation cannot fully describe a reaction?
An unbalanced equation (skeleton equation) only indicates the nature of the reactants and products but tells nothing of the stoichiometric ratios, i.e. it tells nothing of how much of each species is present, not which reactant might be in excess or limiting, etc.

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 would you change to balance a chemical equation?
You can balance a chemical equation by adjusting the coefficients of the compounds involved. Start by balancing the atoms that appear in only one reactant and one product, then balance the atoms that appear in more than one compound. Finally, check that the equation is balanced by verifying that the number of each type of atom is the same on both sides of the equation.
Why cant the subscripts of a chemical equation be changed?
The subscripts in a chemical equation represent the number of atoms of each element involved in the reaction. Changing the subscripts would alter the stoichiometry of the reaction, resulting in a different chemical compound being formed. This would violate the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Therefore, the subscripts in a chemical equation must remain constant to accurately represent the reactants and products involved.
Why must a chemical equation be balanced before you can determine the mole ratio?
A balanced chemical equation ensures that the law of conservation of mass is followed, meaning the same number of atoms of each element are present on both sides of the equation. Without a balanced equation, the mole ratio would be inaccurate because the amounts of substances would not be properly accounted for in the reaction.
