In the balanced equation for photosynthesis, \(6CO_2 + 6H_2O → C_6H_{12}O_6 + ?\), the missing part on the product side is the oxygen gas (O₂) released during the process of photosynthesis. To find the missing product:
Let's count the atoms on the left side:
- 6 carbon atoms from \(6CO_2\)
- 6 hydrogen atoms from \(6H_2O\)
- 6 × 2 = 12 oxygen atoms from \(6CO_2\) + 6 from \(6H_2O\), giving a total of 18 oxygen atoms.
On the right side, in \(C_6H_{12}O_6\):
- 6 carbon atoms
- 12 hydrogen atoms
- 6 oxygen atoms
To balance the oxygen:
18 oxygen atoms (left) - 6 oxygen atoms (in glucose) = 12 oxygen atoms are released as \(O_2\).
Thus, the missing part from the product side is **6O₂** (which corresponds to 12 oxygen atoms).
The final balanced reaction is:
\[6CO_2 + 6H_2O → C_6H_{12}O_6 + 6O_2\]
So the answer is **12 oxygen atoms** (from 6O₂).

Thus, the missing part from the product side is **6O₂** (which corresponds to 12 oxygen atoms).
The final balanced reaction is:

So the answer is **12 oxygen atoms** (from 6O₂).
