Will give brainliest if i can figure out how When is the small size of gas particles taken into account?

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 !

m=9

step-by-step explanation:

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

give me abc and i will get it for u.
