Answer:
Compound
Explanation:
We want to know if it's a compound or a mixture.
An example of a mixture is salt water: you can heat it hot enough to boil off the water, leaving only the salt. This is a physical change, which is how you know it's a mixture.
Something like gold is a compound: if you heat it, or hit it, you'll still only have gold. You can only break it down by chemical means, which is how you know it's a compound.

Answer: 0.0257 moles of
and 0.0257 moles of ![SO_4^{2-}](https://tex.z-dn.net/?f=SO_4%5E%7B2-%7D)
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
![Molarity=\frac{moles}{\text {Volume in L}}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7Bmoles%7D%7B%5Ctext%20%7BVolume%20in%20L%7D%7D)
moles of ![Fe_2(SO_4)_3=Molarity\times {\text {Volume in L}}=0.147\times 0.175L=0.0257moles](https://tex.z-dn.net/?f=Fe_2%28SO_4%29_3%3DMolarity%5Ctimes%20%7B%5Ctext%20%7BVolume%20in%20L%7D%7D%3D0.147%5Ctimes%200.175L%3D0.0257moles)
The balanced reaction for dissociation will be:
According to stoichiometry:
1 mole of
gives 1 mole of
and 1 mole of ![SO_4^{2-}](https://tex.z-dn.net/?f=SO_4%5E%7B2-%7D)
Thus there will be 0.0257 moles of
and 0.0257 moles of ![SO_4^{2-}](https://tex.z-dn.net/?f=SO_4%5E%7B2-%7D)
