What chemical test (axcept a magnet) to use to distinguish between iron and sulphur?

Heat both. Fe won't burn. S will burn AND it produces SO2, a gas of noxious fumes.

To distinguish between iron and sulfur without using a magnet, you can perform a chemical test called a "burning test." Here's how to conduct this test:

1. Obtain a small sample of the material you want to identify, containing both the iron and sulfur.
2. Place the sample on a non-flammable surface or in a heat-resistant dish.
3. Use a flame source, such as a Bunsen burner or a butane lighter, to heat the sample.
4. Observe the reaction:

a. If the sample emits a yellowish-greenish flame, it indicates the presence of sulfur. Sulfur has a lower ignition temperature than iron, so it readily burns and produces this characteristic color.

b. If the sample does not emit a colored flame and simply turns red, it indicates the presence of iron. Iron does not readily burn in normal atmospheric conditions, so it will exhibit a red glow without any distinct flame color.

Please note that it's crucial to handle any chemical substances with care and adhere to safety precautions. Additionally, this test is only suitable for small amounts of material and shouldn't be used for large quantities or bulk samples.
