Answer:
iron fillings
Explanation:
From the question,
We know that common salt, water, and copper sulphate is the compound.
Common Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite.
Water (chemical formula H2O) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, even though it provides neither food, energy, nor organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure.
Copper sulfate, also known as copper sulphate, is an inorganic compound with the chemical formula CuSO4. It forms hydrates CuSO4·nH2O, where n can range from 1 to 7. The pentahydrate (n = 5) is the most common hydrate of copper(II) sulfate.
All three are compound but Iron fillings are not a compound because Iron filings are very small pieces of iron that look like a light powder. As the name suggests, iron filings were traditionally obtained from metal working operations as the scrap material filed off larger iron and steel parts.
