Answer:
+3
Explanation:
The oxygen all have a -2 oxidation state. (peroxides are exceptions)
The chemical structure is symmetrical. Both carbon are equivalent.
2 (oxidation state of carbon) + 4 (oxidation state of oxygen) = charge of ion.
2 (oxidation state of carbon) + 4 (-2) = -2
oxidation state of carbon = +3

Answer:
Na₃PO₄ + 3HCl —> 3NaCl + H₃PO₄
The coefficients are: 1, 3, 3, 1
Explanation:
_Na₃PO₄ + __HCl —> __NaCl + _H₃PO₄
The above equation can be balance as follow:
Na₃PO₄ + HCl —> NaCl + H₃PO₄
There are 3 atoms of Na on the left side and 1 atom on the right side. It can be balance by writing 3 before NaCl as shown below:
Na₃PO₄ + HCl —> 3NaCl + H₃PO₄
There are 3 atoms of Cl on the right side and 1 atom on the left side. It can be balance by writing 3 before HCl as shown below:
Na₃PO₄ + 3HCl —> 3NaCl + H₃PO₄
Now, the equation is balanced.
The coefficients are: 1, 3, 3, 1
Because the sulfur ion has a negative two charge, the formula would be Fe2S3
Divide the number of molecules you have by, 6.022 x 10^23. This will give you the moles of water, or the moles of anything, since there is always 6.022 x 10^23 molecules in 1 mole of substance.
1.23x10^24 atoms/6.022x10^23 atom/mole = 2.04 mole H20
