Are salt sugar and water mixtures or compounds?
Salt, sugar, and water are all mixtures. A mixture is a combination of two or more substances that are physically intermingled but retain their individual properties. In the case of salt sugar and water, each component can be separated by physical means, such as filtration or evaporation.
Sugar crystals are separated from a sugar syrup by evaporation of water is a chemical reaction or physical reaction?
The separation of sugar crystals from a sugar syrup by evaporating water is a physical process, not a chemical reaction. This is because no new substances are formed during the process—the sugar molecules remain the same whether in the syrup or as crystals.
What changes does dissolving sugar in water have?
Dissolving sugar in water is a physical change where the sugar crystals break down and mix evenly with the water molecules. This forms a homogeneous mixture known as a solution. The sweetness and properties of the sugar are retained, but the sugar can no longer be separated from the water by filtration.
When sugar is added to water the sugar dissolves and the resulting liquid is clear. Do the sugar and water form a pure substance or do they form a mixture?
A clear solution of sugar in water is a mixture, not a pure compound, because the proportions between sugar and water can be continuously varied and the two individual compounds can be recovered, for example by vaporizing the water in the solution under vacuum.
Which of these outcomes is conclusive evidence that mixing sugar in water is a physical change?
The ability to separate the sugar and water through physical means (such as evaporation) would be conclusive evidence that mixing sugar in water is a physical change. This shows that the properties of both the sugar and water have not changed chemically, indicating a physical rather than a chemical change.
Is sugar and water a mixture or pure substance?
Sugar and water form a mixture when combined because they do not chemically bond to create a new substance. Each component retains its chemical properties and can be separated by physical means, such as evaporation.

Is carbonated water a compound element or a mixture?
It can be separated by physical means, so therefore it is a mixture.
Can sugar water be separated?
Yes. The water can be evaporated, leaving behind the sugar.

How can coriander leaves and sugar crystals be separated?
Sugar is soluble in water.
Would the separation mixture of sugar and water be separated by density?
Sugar and water are separated by crystallisation. Though there are other methods this is the easy and obvious one.
How could you decide whether the dissolving of sugar in water is a physical or chemical change?
You can evaporate the water and recover the sugar unchanged. A chemical change means a chemical reaction has taken place and changed the substance chemically. A physical change means that a solid has become a liquid such as dissolving sugar.
How can sugar and water be separated?
Sugar and water can be separated by using a couple different methods. One method is by using an apparatus for distillation. Another is by using evaporation.
