Question

Identify the principle of separation.
i. raw rice and lentils
ii. sulphur and iron filings
iii. sand and sawdust
iv. oil and water
V. ammonium chloride, salt and sand​

Answer 1

Explanation:

principal of separation for raw rice and lentils is the difference in weight because the weight of the rice is greater than that of the lentils

Iron and sulfur react together when they are heated to make a compound called iron sulfide. Here are some of the differences between a mixture of iron and sulfur, and iron sulfide: ... you can separate the iron from the mixture using a magnet, but this does not work for iron sulfide

gravity method

Two immiscible liquids, oil and water, can be separated by using Separating Funnel. The process involves using the mixtures of unequal particle density. Because water is denser than oil, it can be separated by means of the funnel and left in the funnel with an oil layer.

Ammonium chloride sublime and can be separated from the mixture of salt and sand by the process of sublimation.
