Answer:

Explanation:
Carbon disulphide is the liquid that can be used to separate iron fillings and sulphur powder.
When carbon disulphide is poured into the dish, the sulphur powder gets easily dissolved in the carbon disulfide. The iron fillings are left to settle on the bottom of the dish.
The iron fillings can get seperated through filtration. When the mixture of sulphur powder and carbon disulphide gets completely evaporated, the sulphur powder is left over.
The answer is Solid.
This is on account of the substances that develop a solid are packed in a settled, firmly pressed geometric plan.
1: viewing any chemical reaction in a laboratory
2: dangerous to look at when it burns & used in photography, fireworks, and flares
3: the product
The molar mass for PCL3 is 137.33 g/mol
The last photo because its molecular formula is C3H4.
