Filtration. :)
One appropriate process to separate a mixture is chromatography. In chromatography, the mixture is dissolved in a solvent and then passed through a stationary phase where components separate based on their affinity for the stationary phase. This allows for the individual components of the mixture to be identified and collected.
It wouldn't be a single substance, it would be a mixture.
Yes. Salad is a heterogeneous mixture. Though it uses many differnet ingredients they never combine and can be separated. An apple pie would be an homogeneous mixture because the ingredients combine when baked and can't be separated.
physical mixture of the two substances, as they do not chemically react with each other. After shaking, the sugar and sand will be physically mixed together but can be separated by a process such as filtration.
Iron can be separated with a magnet.
An example of a solution being a mixture would be muddy water or saltwater because they can be physically separated.
Sugar and water are separated by crystallisation. Though there are other methods this is the easy and obvious one.
Nail and sand would be considered a heterogeneous mixture because the two substances do not mix uniformly and can be easily separated.
Iron can be separated from sand using a (electro)magnet.
Yes, iced tea granules and water would be considered a mixture. The granules are dissolved in the water but can still be physically separated.
No, a magnet would not be effective in separating salt from water as salt is not magnetic. Instead, the mixture could be separated through the process of evaporation, where the water would be evaporated, leaving the salt behind.
this process would be called diffusion
