Solid aluminium and chlorine gas react to form solid aluminium chloride suppose you have 5.0 mole of aluminium and 2.0 mol of cl2 in a reactor suppose as much as possible of the a L reacts how much will be left

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 !

the increase of protons   hope this

thats a little if u want the answer just look it up on google thats what i do haha : )
