To balance the given chemical equation:
NaOH + FeSO4 → Na2SO4 + Fe(OH)2
We need to ensure that the number of each type of atom on the reactant side equals the number on the product side.
- Sodium (Na): There are 2 sodium atoms in Na2SO4, so we need 2 NaOH, giving us 2 sodium atoms.
- Sulfate (SO4): There is 1 sulfate ion in FeSO4, and in the balanced equation, we need to have 1 Na2SO4.
- Iron (Fe): There is 1 iron atom in FeSO4, and 1 iron atom in Fe(OH)2, so we have 1 on each side.
- Hydroxide (OH): We need 2 hydroxide ions to balance with Fe(OH)2, which matches the 2 NaOH.
Hence, the balanced equation is:
2NaOH + FeSO4 → Na2SO4 + Fe(OH)2
Thus, the correct option showing the balanced chemical equation is:
2NaOH + FeSO4 → Na2SO4 + Fe(OH)2 (in any form that matches, including with or without spaces).
The last option seems to be repeated in the responses without specific balancing. Would you want to share the options formatted or by grouping to clarify?
