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.
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.
Why can sand and sugar can be separated?
Sand and sugar can be separated due to their differing physical properties, primarily solubility. Sugar is soluble in water, meaning it dissolves when mixed, while sand is not. By adding water to a mixture of sand and sugar, the sugar dissolves, allowing the sand to be filtered out through a sieve or filter paper. This process takes advantage of their distinct behaviors in a liquid medium.
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.
Is lemon juice plus sugar plus water a compound or a mixture?
Lemon juice plus sugar plus water is a mixture, not a compound. In a mixture, the individual components retain their own properties and can be separated by physical means. In this case, the lemon juice, sugar, and water can be combined, but they do not chemically bond to form a new substance.

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.

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.
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.
