Question

This question has two parts. First, answer Part A. Then answer Part B.

Part A
The equation for photosynthesis is shown below.

6CO2+ 6H2O → C6H12O6+ 6O2


There are 18 total oxygen atoms present in the reactants. How many total oxygen atoms are present in the products?
A.
2
B.
6
C.
12
D.
18

Answer 1

To determine the total number of oxygen atoms present in the products of the photosynthesis reaction, we can analyze the products given in the equation:

6CO2 + 6H2O → C6H12O6 + 6O2

In the products:
- C6H12O6 (glucose) contains 6 oxygen atoms.
- 6O2 (oxygen gas) contains \(6 \times 2 = 12\) oxygen atoms.

Now, we can add the number of oxygen atoms in both products:
- From C6H12O6: 6 oxygen atoms
- From 6O2: 12 oxygen atoms

Total oxygen atoms in the products = 6 + 12 = 18.

So, the answer is:
D. 18
