While Bob is studying waves in science and he learns that the energy of a wave is directly proportional to the square of the Waves amplitude if the amplitude of a wave changes from to meet to form what should you predict as the effect on energy of the wave

i have a feeling this is a gay person trolling to make straights look bad.

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 !
