It depends on the direction of the arrow.
If the arrow goes like this ---> the reactant would be 2Fe2O3
If the arrow goes like this <--- the reactants would be 4Fe + 3O2
C) landslides.
Explanation:
Landslides is not a way in which mountains are built on earth. It is a destructive process in nature that causes the slumping and wasting of land masses.
Landslide is a form of mass wasting and does no build masses.
Volcanoes helps to build mountains on the crust and this way, igneous rocks are formed.
Deposition process upbuilds to form sedimentary rocks.
Faulting is a can also be a constructive process that builds a mountain in the case of horsts and graben

The answer is A, I’m pretty sure, I remember learning this a few years ago, I hope you get it right :)
Physical changes occur when substances are mixed but don't chemically react.
Explanation:
Please provide the chemical reaction to allow others to help solve this problem. Assuming the system is in STP, then use the molar volume to solve for the moles of Oxygen and then use the mole ratio to determine the moles of NO2 that is produced as a result of this reactant
