Question

write a problem question for this descriptive investigation. how can the mixture of sand, gravel, iron fillings, salt, and water be separated into individual components? procedures 1 - describe each of the components in table 1. if you do not know if something is an element or a compound, do research. 2 - mix the ingredients in the bowl. describe the properties of the mixture. is it heterogeneous or homogeneous?

Explanation:

Step1: Identify component properties

Sand is a solid granular material, gravel is larger - sized solid particles, iron filings are magnetic solid particles, salt is a soluble solid in water, and water is a liquid.

Step2: Determine separation methods

Use a magnet to separate iron filings first as they are magnetic. Then, filter the mixture to separate sand and gravel (insoluble solids) from the salt - water solution. Finally, evaporate the water from the salt - water solution to get salt.

Answer:

First, use a magnet to remove iron filings. Then, filter the mixture to separate sand and gravel from the salt - water solution. Evaporate the water from the salt - water solution to obtain salt.
