decomposition

Explanation:

2KClO3 → 2KCl + 3O2 is decomposition reaction. Decomposition reaction is a type of chemical reaction that involves breaking down compound into smaller or individual elements.

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
