Can a mixture of powdered salt and sugar can be separated by winnowing?
No, winnowing involves separating components based on weight through blowing air. Powdered salt and sugar have similar weights and sizes, making it difficult to separate them effectively via winnowing. Other methods like dissolving in water or using a sieve might be more appropriate.
Is sawdust better then using salt?
Using sawdust for spill cleanup is generally better than using salt because sawdust is more absorbent and can help contain spills more effectively. Sawdust also poses less risk to the environment compared to salt, which can contaminate soil and water sources.
How can a mixture of nails and sawdust be most efficiently separated into its component parts?
A mixture of nails and sawdust can be efficiently separated using a magnet. By passing a magnet over the mixture, the ferromagnetic nails will be attracted to the magnet, allowing them to be easily removed from the sawdust. The remaining sawdust can then be collected separately, resulting in an effective separation of the two components.
How do you separate sand salt and sawdust into pure states?
If all three are mixed together you can separate the sawdust from the group with a Sieve filter with holes smaller than the sawdust, but larger than the sand/salt particles. You could then use another sieve, if the sand and salt particles are significantly different in size,...OR add water to the mix....the salt will dissolve into solution leaving the sand behind. Pour off the water and let it evaporate, leaving the salt behind. Put the mixture of sand, salt and sawdust into a quantity of water: the sand will sink to the bottom, sawdust will float and salt will dissolve. Skim off (and dry) the floating sawdust. Pour off the water containing the dissolved salt. This is then heated to cause all the water to evaporate (leaving behind the salt). The remaining residue in the original container (wet sand) can now be dried off with heat.
How do you separate sawdust from salt and sand without using water?
If the particles are each of different size, these compounds may be separated based on two selective filtrations using appropriately-sized sieves. If this process is not possible, than separation may be accomplished by dissolving the salt in another polar solvent such as liquid ammonia or methanol (about 1 or 2 grams of NaCl will dissolve per 100mL of these solvents). The sand and sawdust could then be separated using their density, as the sawdust would float and the sand would sink. Evaporation the solvent would yield the solid salt.
Can a mixture of powdered salt and sugar can be separated by winnowing?

How can you separate a mixture of sand salt and sawdust?
To separate a mixture of sand, salt, and sawdust, you can use a combination of physical separation techniques. Firstly, use a sieve to separate the sawdust from the sand. Then, dissolve the salt in water, leaving the sand behind. After the salt has dissolved, use evaporation to recover the salt, leaving the sand separated.
Is sugar heavier than salt?
Yes
Can you filter it to separate salt sawdust and gravel?
Yes, you can separate salt, sawdust, and gravel using a combination of techniques such as sieving, filtration, and evaporation. First, use a sieve to separate the gravel from the rest. Then, mix the salt and sawdust with water to dissolve the salt, leaving the sawdust behind. Finally, use a filter to separate the sawdust from the saltwater solution. By evaporating the water, you can recover the salt crystals.

How could separate the mixture of salt water and saw dust?
Add the mixture of sawdust, sand and salt to water. The sawdust will float and can be skimmed form the surface. The salt will dissolve in the water. The sand can be filtered from the mixture which remains. The salt water solution which remains can be heated and the water will evaporate leaving the salt behind.
Why do sawdust in water cannot be separated by sedimentation?
Sawdust in water cannot be separated by sedimentation because sawdust is less dense than water, causing it to remain suspended in the water rather than settling to the bottom. The sawdust particles are too small and lightweight to separate effectively through sedimentation alone. Other methods such as filtration or centrifugation may be more suitable for separating sawdust from water.
What allows a mixture to be separated into its components?
Hand Pricking, sedimentation, decantation, magnetic sepration, filteration, winnowing, sieving.

Why A mixture can be separated by sieving but not by winnowing or handpicking give reason?
due to different size of particles during milling process
Why does using a magnet to separate iron filling from sawdust work?
Iron is magnetic; so, the iron filling is pulled/ is attracted to the magnet. The sawdust is not magnetic, so it will stay where it is, and will eventually be separated from the iron and the magnet.
