Hello there!
I am not really sure which part you are talking about but let me answer some of them.
First, you need to read the information they gave you about glucose etc..
13- What is produced in photosynthesis?
"Photosynthesis is essential for all life on earth, because it provides food and oxygen."
Thus, the answer is: Photosynthesis produced food and oxygen.
14- What is the glucose used for?
"The glucose produced is used by the plant for energy and growth."
Thus, the answer is: The glucose used for energy and growth of the plants.
15- What is the oxygen used for?
"The oxygen produced is released into the air for us to breath."
Thus, the answer is: The oxygen used for us to breath.
I hope this helps!
Let me know if you have questions about the answer.
All the given species have the same charge except peroxide.
<h3>Charges on ions</h3>
- The charge on monohydrogen phosphate is negative because of its formula,
![[HPO4]^{2-}](https://tex.z-dn.net/?f=%5BHPO4%5D%5E%7B2-%7D)
.
- The charge on permanganate is negative. The formula is
- The charge of oxide (
) is negative.
- The charge on peroxide is ( R−O−O−R) is neutral.
- The charge on oxalate,
, is negative.
Thus, only peroxide is unique.

Answer: (2)3.0 mol
Explanation: 222.3g= 222.3/74= 3.0 mol
1mol Ca(OH)2 is 74g
I think B would be the most reasonable answer, the steps all seem to make sense
