Added together = 159.7 grams for one mole of Fe2O3<span>. That is moles of hematite, but the question is about iron. We can see there are </span>two<span> iron atoms for every hematite molecule. So the number (moles) of iron atoms is twice the moles of the hematite molecules.
so depending on how much you initially have will determine the answer</span>
It would be 5.0 more in i did this
In balancing reactions, the number of atoms on each side should be of equal number. It is the most important rule in reactions. Also, we should know the correct substances involved in the reaction. We do as follows:
2K + MgBr2 = 2KBr + Mg
The movement of water on and above the earth's surface is called the hydrologic cycle, or the water cycle. Hope this helps!
The correct answer among the choices given is the first option.The teacher most likely is talking about distillation of a mixture.
