Answer 2

Task 1: Dissolving Sugar in Water

When sugar is dissolved in water, it undergoes a process called dissolution. Dissolution is a physical process in which a solute (in this case, sugar) is dispersed uniformly in a solvent (in this case, water) to form a homogeneous mixture called a solution. The sugar molecules separate and disperse throughout the water molecules, resulting in a clear, sweet-tasting liquid.

Task 2: Reaction of Vinegar with Baking Soda

When vinegar (acetic acid) reacts with baking soda (sodium bicarbonate), a chemical reaction occurs, resulting in the formation of carbon dioxide gas, water, and a salt called sodium acetate. This reaction is commonly known as an acid-base reaction or a neutralization reaction.

The chemical equation for this reaction is as follows: ``` CH3COOH (acetic acid) + NaHCO3 (sodium bicarbonate) → CO2 (carbon dioxide) + H2O (water) + CH3COONa (sodium acetate) ```

During the reaction, carbon dioxide gas is released as bubbles, causing the mixture to fizz and expand. This is because the reaction produces carbon dioxide gas in the form of bubbles. The fizzing and expansion are observable phenomena.

General Conclusion

In both tasks, we observed different phenomena. In the first task, the sugar dissolved in water, which is a physical process called dissolution. In the second task, the vinegar reacted with baking soda, resulting in the release of carbon dioxide gas and the formation of water and sodium acetate. This is a chemical reaction known as an acid-base reaction or neutralization reaction.

It is important to note that these observations and explanations are based on the information provided. If you have any specific questions or need further clarification, please let me know!
