Flour can be separated from the mixture by sieving as they are fine particles.
Peanuts can be separated from the rice by handpicking as they are bigger in size.
Sand+salt: a heterogeneous mixture.
- Sand is separated by filtration- Kerosene is separated by decantation (or with a special separation funnel) from water
A mixture can be separated by physical properties such as differences in boiling points, solubility, density, or magnetic properties. For example, a mixture of salt and sand can be separated by dissolving the salt in water and then filtering out the sand, as salt is soluble in water and sand is not.
To separate flour, sand, and sulfur, you can use a combination of techniques. First, use a sieve to separate the sand from the flour. Next, mix the remaining mixture with carbon disulfide to dissolve the sulfur. After the sulfur has dissolved, filter the mixture to separate the sulfur solution and the leftover flour particles.
water and sand there is dissolved sugar or salt with sand
If you think to sedimentation it is possible.
Explain how a mixture of sand and salt can be separated.
1. Filteration2. Sedimentation3. Evaporation
Sand in water is a mixture. Because you can differentiate between the sand and water, it is a heterogeneous mixture.
Iron can be separated from sand using a (electro)magnet.
A mixture of water and sand can be separated by stirring the mixture to dissolve the sand in water, followed by filtering the mixture using filter paper. The sand will be left behind as residue on the filter paper, while the water passes through as filtrate.
Heterogeneous mixtures are mixtures that can easily be separated. For instance, sand mixed with water is a heterogeneous mixture that can be separated by filtration. Another example of a heterogeneous mixture is salt mixed with pebbles, which can be separated by adding water to the mixture.
