In an atom, the electron's spin around the center, also called the nucleus. The electrons like to be in separate shells/orbitals. Shell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell, three can hold a maximum of eight electrons. ( This is the answer to both questions!)

Answer:
![n_{C_2O_4^{2-}}=1.59mol C_2O_4^{2-}](https://tex.z-dn.net/?f=n_%7BC_2O_4%5E%7B2-%7D%7D%3D1.59mol%20C_2O_4%5E%7B2-%7D)
Explanation:
Hello there!
In this case, according to the given information and chemical equation, it turns out possible for us to calculate the moles of C2O4^2- by firstly setting up the equilibrium expression:
![Kc=\frac{[[Fe(C_2O_4)_3]^{3-}]}{[Fe^{3+}][C_2O_4^{2-}]^3}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5B%5BFe%28C_2O_4%29_3%5D%5E%7B3-%7D%5D%7D%7B%5BFe%5E%7B3%2B%7D%5D%5BC_2O_4%5E%7B2-%7D%5D%5E3%7D)
However, according to the question, we just need to apply the given 1:3 mole ratio in the chemical reaction, of iron (III) ions to oxalate ions to obtain:
![n_{C_2O_4^{2-}}=0.53molFe^{3+}*\frac{3molC_2O_4^{2-}}{1molFe^{3+}}=1.59mol C_2O_4^{2-}](https://tex.z-dn.net/?f=n_%7BC_2O_4%5E%7B2-%7D%7D%3D0.53molFe%5E%7B3%2B%7D%2A%5Cfrac%7B3molC_2O_4%5E%7B2-%7D%7D%7B1molFe%5E%7B3%2B%7D%7D%3D1.59mol%20C_2O_4%5E%7B2-%7D)
