This is the process where wind, water or ice may add a layer of sediment to a landform.

Deposition...

Explanation:

Deposition is a process in which the water, ice and wind for layers of sediments when the fluid flow loses it's kinetic energy. After losing energy, the flow of soil in restricted and a layer over layer of soil is formed by deposition called sediments.

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 !
