a slow-moving mass of ice has gradually weathered and eroded rock away in a mountain valley. The landscape of rock has greatly changed. Which sphere was affected in the transformation?

Geosphere

Explanation:

The sphere that was affected by this transformation is the geosphere.

The geosphere is the solid part of the earth which is made up of rocks and soils.

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 answer is 303.15 or 303
