Number of moles of FeCl2 used = mass/ molar mass
Number of moles = 507/126.751 = 4.
If one mole of Fe reacts with two moles of sodium
Then 4 moles of Fe produces 8 moles of sodium.
Number of moles of sodium = mass/molar mass
Molar mass of sodium chloride = 23 +35.5 = 58.5 g/mol
Hence mass = 8 * 58.5 = 468 g. Hence Option A.
Sodium can only be separated from Chloride by chemical means e.g. electrolysis.
The boundaries of Earth's plates. Before lava reaches the surface, the molten material is called<span> magma.

<h2>Answer : Solid</h2><h3>Explanation :</h3>
When the substance was tested in the lab it was seen that it maintains a unique shape, which is the differentiating property of solids. Also, they are very good conductors of electricity. Solid contains electrons, protons and neutrons this is a common thing which is found in every state of matter. This all details confirms that it will be solid.
Answer:
It is soft and white. It has a low melting and boiling point, a good conductor electricity, and reacts with water. Furthermore, it is also highly reactive, malleable, and ductile.
