dissolve;not dissolve
Name 3 examples of a mixture
sand and water
powder and water
marbles and paperclips
When I mix salt and water together and the let the water evaportate,what can I tell about the mass of the salt?
The mass will be the same
Name 2 things that are soluble in water
salt
citric fruit
To determine what would happen if you mixed sugar and sand into water, you can use your knowledge of solubility. Sugar is soluble in water, so it would dissolve and become evenly distributed throughout the water. On the other hand, sand is insoluble in water, so it would not dissolve and would remain separate from the water.
Examples of mixtures can be found all around us. Here are three examples:
1. Mixing sand and water together creates a mixture where the sand particles are suspended in the water.
2. Mixing powder and water creates a mixture where the powder particles are dispersed throughout the water.
3. Mixing marbles and paperclips together creates a mixture where the marbles and paperclips are physically combined, but maintain their individual properties.
When you mix salt and water together, the salt dissolves in the water and forms a homogeneous mixture. If you let the water evaporate, the water molecules will escape into the air, leaving behind the salt crystals. Since the process of evaporation only removes the water, the mass of the salt will remain the same.
Two examples of substances that are soluble in water are salt (sodium chloride) and citric fruit (such as the juice of a lemon or lime). When added to water, they both dissolve and form a solution.
When sugar is mixed with water, it will dissolve, meaning it will mix completely with the water and form a homogeneous solution. On the other hand, when sand is mixed with water, it will not dissolve and will remain as separate particles. This mixture is considered heterogeneous.
Three examples of mixtures could be sand and water, where sand particles are mixed with water but do not dissolve; powder and water, where the powder particles may dissolve or not dissolve depending on the substance; and marbles and paperclips, where two solid objects are physically mixed but not dissolved in each other.
When you mix salt and water together and let the water evaporate, the mass of the salt will remain the same. This is because during evaporation, the water molecules evaporate into the air leaving behind the solid salt particles. The mass of the salt does not change unless there is a chemical reaction taking place.
