Hey there! :D
During the process of photosynthesis, leaves turn carbon dioxide and water into glucose and oxygen. (glucose is just a fancy word for sugar)
So "A" is correct.
We need trees to make oxygen as a waste, or product, of the reaction. Similarly, we take in oxygen and breathe out carbon dioxide. As a cycle.
I hope this helps!

Answer: The empirical formula of one that contains 30.45% nitrogen is 
.
Explanation:
Given: Mass of nitrogen = 30.45 g
Let us assume that the mass of given oxide is 100 grams.
As the atomic mass of nitrogen is 14.0067 g. So, moles of nitrogen will be calculated as follows.
Also, mass of oxygen = (100 - 30.45) g = 69.55 g
Atomic mass of oxygen is 15.9994 g/mol. So, moles of oxygen will be as follows.
The ratio of both the atoms is as follows.
This means that gas has 2 moles of oxygen to 1 mole of nitrogen. Hence, the formula of oxide is .
Thus, we can conclude that the empirical formula of one that contains 30.45% nitrogen is .
