**Question 3: Predict the Sign of ΔS**

a) Osmosis

b) Dropping a beaker

c) Unbalanced chemical equation:

\[ \text{C}_2\text{H}_6 (g) + \text{O}_2 (g) \rightarrow \text{CO}_2 (g) + \text{H}_2\text{O} (g) \]

**Explanation**: 

- **Osmosis**: This process typically involves the movement of solvent molecules through a semipermeable membrane from a region of lower concentration to one of higher concentration. Analyze whether this increases or decreases system disorder.

- **Dropping a beaker**: Consider how the physical act of dropping and potentially breaking a beaker affects the randomness or disorder of the system involved.

- **Combustion Reaction**: With the unbalanced equation given, assess the change in the number of gaseous molecules on each side to determine whether the entropy (ΔS) increases or decreases. Balancing the equation first could be beneficial for clarity.
