Chalk is Calcium Carbonate, aka CaCO3, so it's only one substance.
No, a mixture of sugar and chalk is considered heterogeneous. This is because sugar and chalk do not dissolve in each other, so they would have visible differences and not form a uniform composition throughout the mixture.
Yes, water and chalk would be considered a mixture in chemistry. A mixture is a combination of two or more substances that are not chemically bonded together. In the case of water and chalk, the chalk particles are simply dispersed in the water without any chemical reaction occurring between them.
No, a mixture of chalk and water is not a colloid. A colloid is a mixture where one substance is evenly dispersed in another substance, forming a homogeneous mixture. Since chalk does not form a homogeneous mixture with water, it is not considered a colloid.
Use a magnet to remove the iron filings from the mixture, then mix the remaining components with water. The copper sulfate will dissolve but the CaCO3 (chalk powder) will not. Filter the mixture to remove the chalk, then boil the water to recover the copper sulfate.
a solution is a mixture as a solution is made only when two substances are mixed together so a solution is definitely a mixture!
To separate salt from chalk, you can dissolve the mixture in water. Salt is soluble in water while chalk is not. After dissolving, you can filter the mixture to separate the insoluble chalk from the salt solution. By evaporating the water from the salt solution, you can obtain the salt crystals.
To separate chalk from a mixture of chalk and copper sulfate solution, you can add water to dissolve the copper sulfate, leaving behind the chalk. The water-soluble copper sulfate will form a blue solution, allowing you to filter out the chalk residue, which is insoluble in water.
it is a suspension because; suspension = a solid and a liquid mixing which is what chalk dust and water is. :)

we can filter the mixture of table salt and chalk dust by using the process called filtration because when you mix the table salt with water and chalk dust together, it becomes an insoluble mixture called suspension

it is a mixture of white paint and white chalk
One way to separate chalk and copper sulfate is through filtration. The copper sulfate (being soluble) can be dissolved in water to form a solution, while the chalk remains as a solid. The mixture can then be filtered, allowing the solids (chalk) to be retained on the filter paper while the liquid (copper sulfate solution) passes through.
