The correct answer is:
d) surface area
Grinding a Tylenol tablet into powder increases the surface area, which in turn increases the rate of reaction.

Question 2: The correct answer is:
b) 1 valence electron
Potassium (K) is in Group 1 of the periodic table, which means it has 1 valence electron.
Question 3: To determine the number of atoms in the products, consider the reaction:
1 molecule of Iodine (I2) contains 2 iodine atoms. 2 molecules of Sodium Chloride (NaCl) contain 2 sodium atoms and 2 chloride atoms.
Hence, the total number of atoms in the products is:
- Iodine: 2 atoms
- Sodium: 2 atoms
- Chlorine: 2 atoms
Adding these together gives: 2 (I) + 2 (Na) + 2 (Cl) = 6 atoms.
The correct answer is:
d) 6
