Can salt and sawdust be separated by winnowing?
No, salt and sawdust cannot be separated by winnowing. Winnowing is a process that uses air flow to separate lighter particles like chaff from heavier particles like grains. Since both salt and sawdust are fine particles, they would not separate effectively through winnowing.
Can sulphur powder be filtered?
No, sulphur powder cannot be filtered because it is a fine powder that will pass through filter paper along with the liquid. Instead, sulphur powder can be separated from a liquid by methods such as precipitation or sedimentation.
Small particles that cannot be removed by simple filtration However they often can be separated through?
Small particles that cannot be removed by simple filtration are typically colloids. These particles can often be separated through techniques such as centrifugation, sedimentation, or using specialized filters like ultrafiltration or dialysis, which can help isolate the colloidal particles from the solution. These methods utilize differences in size, density, or charge to separate the particles effectively.
Can aspirin be physical separated?
Yes, aspirin can be physically separated through processes like crystallization or chromatography. These methods exploit differences in solubility or other physical properties to isolate aspirin from other compounds present in a mixture.
What is a substance that cannot be separated into simpler substances by physical or mechanical methods such as filtering boiling or sifting?

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.
Why sawdust mixed in water cannot be sepearated by sedimentation?
Sawdust mixed in water cannot be separated by sedimentation because sawdust particles are too light to settle quickly in water. The buoyant force acting on the sawdust particles is stronger than the gravitational force pulling them down, so they remain suspended in the water for a long time. This makes it difficult for the sawdust to separate and settle at the bottom through sedimentation.
Can be separated by physical methods?
No, compounds cannot be separated by physical methods. Because of their chemical bonds, they can only be separated by chemical methods.
Can salt and sawdust be separated by winnowing?
No, salt and sawdust cannot be separated by winnowing. Winnowing is a process that uses air flow to separate lighter particles like chaff from heavier particles like grains. Since both salt and sawdust are fine particles, they would not separate effectively through winnowing.
Can sulphur powder be filtered?
No, sulphur powder cannot be filtered because it is a fine powder that will pass through filter paper along with the liquid. Instead, sulphur powder can be separated from a liquid by methods such as precipitation or sedimentation.
Mixtures cannot be separated true or false?
False. Mixtures can be separated using various methods such as filtration, distillation, chromatography, and evaporation.

What is the method called that is used to separate sawdust from water?
Filtration is the most simple method.
Is mixture of sand and sawdust is separated by filtration?
You can not separate a mixture of sawdust and sand through filtration process as both of these materials do not pass through the filter paper in the filtration funnel after mixing them in water.
Is sawdust an element compound or a mixture and how do you know which it is?
Sawdust is a mixture because it is composed of different elements and compounds, such as cellulose, lignin, and hemicellulose. Mixtures can be separated into their individual components through physical means, such as filtering or distillation, without changing the properties of the substances. Elements and compounds, on the other hand, combine in fixed ratios and cannot be separated into simpler substances by physical means.
Can aspirin be physical separated?
Yes, aspirin can be physically separated through processes like crystallization or chromatography. These methods exploit differences in solubility or other physical properties to isolate aspirin from other compounds present in a mixture.
Pure substances can be separated by physical means. true or false?
False. Pure substances cannot be separated by physical means. They are chemically uniform and do not contain any impurities that can be separated through physical methods like filtration or distillation.
