Water will vaporize from the mixture before acetone.






Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then, the remaining liquid is heated to remove the water, leaving a residue of substance B. Which statement about substance A and substance B could be correct?(1 point)

Substance A is rice, and substance B is sugar.
Substance A is rice, and substance B is sugar.

Substance A is alcohol, and substance B is salt.

Substance A is sugar, and substance B is instant coffee.

Respuesta :

the answer would be pulp to make it less concentrated

Pulp

distillation

chromatography

Acetone is captured and cooled.

Substance A is rice, and substance B is sugar.

To separate the components of a mixture the substances to be separated must differ in a given physical property.

In chemistry, there are diverse separation techniques used to separate the components of a mixture. Separation depends on differences in a given physical property such as boiling point, solubility in a solvent, difference in particle size etc.

Filtration can be used to separate a solid from a liquid hence it can be used to separate pulp from orange juice.

To separate water and alcohol, distillation is used because such a separation depends on the difference in the boiling points of water and alcohol. Water boils at a higher temperature than alcohol hence the mixture can be separated by distillation.

Chromatography is a method of separation that is dependent on how quickly a the components of a  mixture move through a stationary phase.

Acetone has a lower boiling point than water hence it collected first and cooled before water.

Clearly, substance A must be a solid since it is filtered out after adding water. Substance B must be a water soluble substance which can be recovered from water by evaporation to dryness. Hence substance A is rice, and substance B is sugar.
