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.
Is it a chemical change when soot is produced and deposited on a metal?
Producing soot by burning something is a chemical change, but when it is deposited on metal (or anything else), that is a not a chemical change.See the Related Questions to the left for more information.
What is the equation for the decomposition of sodium hydroxide?
The dissociation reaction for sodium hydroxide in water is as follows: NaOH(s) ---> Na+(aq) + OH-(aq)
What happens to matter when it undergoes a physical and chemical change?
A chemical change cant be undone and a new substance, so in other words you cant reverse the effects and in the end you get ashes. An example of a chemical change would be burning paper and getting ashes. A physical change can be undone. An example of a physical change would be bending the paper because you can still get the paper back and no new substance is created.
Why cant a mixture have a unique chemical formula?
Because in a mixture, there are no bonds formed between the elements, and therefore the proportions of each element are unknown, for the mixture as a whole. A mixture is not a chemical change.
Why cant an unbalanced chemical equation fully describe a reaction?
An unbalanced chemical equation does not accurately reflect the ratio of reactants and products in a chemical reaction, which can affect the stoichiometry of the reaction. Balancing the equation is necessary to ensure that the law of conservation of mass is obeyed and to correctly represent the chemical species involved in the reaction.
Why mole concept is used in balancing chemical equation?
mole concept is used in balancing chemical reaction because for balancing a reaction u cant change the numbers such as 1,2,3 etc.. in between the compund so as a whole we are changing outside the compound

Does a physical or a chemical change?
A phsical change is something that can be changed but cant be changed back. for example: you can crumple a piece of paper but it is still paper. A chemical change means it has been changed perminetly so for example: If you burn the paper its ashes not paper. it was ashes but youy cant change it back into paper. Hope this helps :)
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)
Why can't subscripts be changed?
Subscripts in chemical formulas cannot be changed because they represent the number of atoms of each element present in the compound and are based on the compound's chemical structure. Changing subscripts would alter the formula and therefore the identity of the compound.
Is baked bread a chemical change?
Yes it is because the chemical properties change and it cannot be reversed.
Why cant a chemical reaction be put back the same?
cause chemical reactions cant be reversed
Can you change a doldrum?
no it cant be chaNGED
Why cant i just write the down all the answer to aliner equation?
Because there is no such thing as "aliner" equation.
