Is sand and chalk a homogeneous mixture?
Sand and chalk are not a homogeneous mixture because they do not have a uniform composition, meaning their components are visibly distinguishable from each other. Sand consists of larger particles like silica, while chalk is composed of calcium carbonate.
Explain Why blackboards are not scratched by chalk but by the sand embedded in the chalk?
Chalk is mostly made of calcium carbonate, which is softer than the materials in blackboards. When the chalk rubs against the blackboard, it does not scratch it because of its softer nature. However, chalk often contains trace amounts of sand or other harder impurities that can cause scratching on the blackboard surface.
By which process can you separate a mixture of naphthalene and chalk powder?
Sublimation can be used to separate naphthalene from chalk powder. Naphthalene sublimes at room temperature, while chalk powder does not, allowing for the separation based on this difference in physical properties.
How do you separate a mixture of sand salt chalk dust and amp iron filings.?
First remove iron filings with a magnet. That leaves sand, salt and chalk dust. Add water which dissolves the salt, and filter leaving the sand and chalk dust on the filter paper. Put that back in water and add acid to dissolve the chalk dust (CaCO3) leaving the sand as a solid. Filter to obtain the sand. The chalk dust will now be in the acid as CO2 and H2O and the Ca salt of the acid.
How do you separate sand and chalk from a mixture?
You can separate sand and chalk by using a separation technique like filtration. First, add water to the mixture to make a slurry, then filter it. The sand will remain on the filter paper while the chalk will pass through with the water.
Explain why blackboards are not scratched by chalk but are scratched by the sand embedded in the chalk?
The hardness of sand is higher.
