Answer:

The correct answer is "Earth’s internal heat engine and the hydrological cycle".

Explanation:

The rock cycle is a geological process that describes the movements and transitions that sedimentary, metamorphic, and igneous rocks going trough. The rock cycle is driving by two main forces: Earth’s internal heat engine and the hydrological cycle. The Earth’s internal heat engine move the inner rocks of Earth from the core to the mantle and viceversa; while the hydrological cycle describes the movement of water, which also have a direct impact on rocks formation and movement.

What is the percent of oxygen by mass in a pure sample of fecr2o4? 1. 52% 2. 13% 3. 37% 4. 7.1% 5. 29%?
Marta_Voda [28]
Let us suppose that we have 1 mol of FeCr2O4. I'm going to use approximate masses because I have no idea what your periodic table will say. Just put in the exact masses from your periodic table.

Fe = 56
Cr*2 = 2*52 = 104
O4 = 4*16 = 64
===========
Total = 56 + 104 + 64 = 224
The % oxygen = (64 / 224) * 100 = 28.5 % but none of your answers match this. Perhaps you are talking about Fe2(Cr2O4)3 The brackets make all the difference in the world.

Without going through all the detail I did before, The molecular mass is
Fe * 2 = 112
Cr * 6 = 312
O * 12 = 192
The total molecular mass = 616

The % Oxygen = (192 / 616) * 100 = 31% roughly. That answer isn't there either. 

Let's wait and see who else answers.
