Question
In the photosynthesis reaction, 6CO2 + 6H2O → C6H12O6 + 6O2, there are 18 oxygen atoms in the reactants. How many oxygen atoms are in the products?Question 28Select one:a.6b.12c.18d.24
Solution
In the photosynthesis reaction, 6CO2 + 6H2O → C6H12O6 + 6O2, the products are glucose (C6H12O6) and oxygen (O2).
- In one molecule of glucose, there are 6 oxygen atoms.
- In 6 molecules of oxygen (O2), there are 12 oxygen atoms (because each molecule of O2 contains 2 oxygen atoms).
So, if you add the oxygen atoms in glucose and oxygen, you get 6 + 12 = 18 oxygen atoms.
Therefore, the answer is c. 18.
