C because it’s talking about the earth and it’s rotating
Workings are in the picture! first you get moles of Fe2O3, then you get moles of Al and then you get mass of Al!
I am not positive this is what you want but here lol:
The Earth's surface is about 71 percent water spreading over many oceans, rivers, and lakes. This also includes the droplets of water on the morning grass, the undrained water from the rain, puddles that never evaporated, etc. As this water is heated up by the Sun, its' molecules start to move faster as it turns into gas and evaporates. As it evaporates it rises, however, the cooler temperatures in the high altitude of Earth's atmosphere make it condense into large clouds. When so much water has evaporated and the cloud very dense, gravity brings down the water from the clouds onto the ground in the form of rain. This completes the water cycle as the water will either turn into runoff, stay on the surface of the Earth, or seep into the ground. Then the water evaporates again, and the whole process starts over.
*Hope this helped!! Have a good night/ day wherever you are! : )*
This reaction contains pure solids which are not considered when writing out equilibrium constant expressions.
O2...........SO2
I 2.9...........0
C -x.......... +x
E 2.9-x........ x
Q=0/2.9 = 0 ---->Q<K Reaction will go to the right
Since the coefficients are all 1, I won't bother putting in the exponents.
k=B/A
1.5= x / (2.9-x)
4.35 - 1.5x = x
2.5x = 4.35
x= 1.74
plug back in ice chart
2.9 - 1.74
=1.16
=1.2 ANSWER
