100% correct

To get the answer to question 1, you need to understand what filtration is. Filtration is a method of separating solid particles from a liquid or gas by passing it through a filter medium. Knowing this, you can determine that filtration is useful for separating solids from liquids or gases.

For question 2, you need to know the appropriate method of separation for a mixture of water and alcohol. In this case, distillation would be the most appropriate method. Distillation is a process that takes advantage of the difference in boiling points of the components in a mixture to separate them. Since water and alcohol have different boiling points, they can be separated by heating and collecting the vapor of the component with the lower boiling point.

To answer question 3, you need to understand the concept of chromatography. Chromatography is a method that separates components of a mixture based on their ability to travel through a medium at different speeds. This separation is due to the differences in the attractions between the components and the medium.

Question 4 requires knowledge of the boiling points of water and acetone. The boiling point of water is 100°C, while the boiling point of acetone is 56°C. Based on this information, you can conclude that during distillation of a mixture of acetone and water, acetone will vaporize from the mixture before water because it has a lower boiling point.

For question 5, you need to analyze the given information. Substance A is filtered out and substance B remains in the liquid after water is added. Then, the liquid is heated to remove the water, leaving substance B. Based on this process, you can infer that substance A is a solid and substance B is a substance that remains in the liquid phase. The answer suggests that substance A is rice (a solid) and substance B is sugar (a substance that dissolves in water).

Overall, you answered all the questions correctly.
