How to write a conclusion on a project work on the topic "seperating mixture"?

To separate these mixtures it was appropriate to understand the physical and chemical structures of all the substances situated within the mixture. After separating these mixtures based on their physical and chemical properties; it was then appropriate to compare their experimental masses compared to their actual masses. Once separating these mixtures and comparing their masses it was important to record any discrepancies which may have been observed throughout the experiment.

Explanation:

The mixture was composed of the following substances;

5.5g sand

2.4g iron fillings

25ml methylated spirits

13g of NaCl

0.6 g of sodium sulfhate

13ml of hexane

The aim of this experiment was to separate a mixture back into its original components based on the mixtures physical and chemical components.

A mixture is when two or more substances are combined by forceful means, such as pouring substances into a container. The molecules of the combined substances then mix with the others to create the forms of solutions, suspensions and colloids. These mixtures can be classified as homogenous or heterogeneous solutions. A heterogeneous mixture contains unevenly distributed liquids, gases and particles. The sand, iron, and hexane are all immiscible substances when mixed in the mixture, therefore many unevenly distributed particles and liquids are present in the mixture, thus categorizing the mixture as a heterogeneous.

the answer is b
