Answer:
26.3 moles of O₂ are needed to react completely with 35.0 mol of FeCl₃
Explanation:
To determine the number of moles of O₂ that are needed to react completely with 35.0 mol of FeCl₃, it is possible to use the reaction stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), and rule of three as follows: if 4 moles of FeCl₃ react with 3 moles of O₂, 35 moles of FeCl₃ with how many moles of O₂ will it react?
moles of O₂= 26.25 ≅ 26.3
<u><em>26.3 moles of O₂ are needed to react completely with 35.0 mol of FeCl₃</em></u>

Answer: Raw data, perhaps.
Explanation: I'm not certain what the question is seeking for an answer, but I would suggest "raw data" would be a reasonable choice. It reflects the data was recorded, but not yet processed to provide a conclusion or observation.
If one were a bit snarky, other possiblities include
- a pile of dung
- my labmate's scrawls, or
- the best web results I could find
Answer:
Decreasing order of strength of the the acids :
Explanation:
The strength of an acid is measured by their pH of aqueous solution.
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
![pH\propto \frac{1}{[H^+]}](https://tex.z-dn.net/?f=pH%5Cpropto%20%5Cfrac%7B1%7D%7B%5BH%5E%2B%5D%7D)
- Lower the pH more will be the hydrogen ions and stronger will be the acid.
- Higher the pH less will be the hydrogen ions and weaker will be the acid.
Solution of HX , has equal number of hydrogen ions as a that of its initial molecules o HX.
![[H^+]_x=[HX]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D_x%3D%5BHX%5D)
Solution of HY , molecules of hydrogen ions are half of the molecules of HY.
![[H^+]_y=\frac{1}{2}[HY]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D_y%3D%5Cfrac%7B1%7D%7B2%7D%5BHY%5D)
Solution of HZ , one quarter molecules of hydrogen ions and three quarter of the molecules of HY.
![[H^+]_z=\frac{1}{4}[HZ]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D_z%3D%5Cfrac%7B1%7D%7B4%7D%5BHZ%5D)
![[H^+]_x>[H^+]_y>[H^+]_z](https://tex.z-dn.net/?f=%5BH%5E%2B%5D_x%3E%5BH%5E%2B%5D_y%3E%5BH%5E%2B%5D_z)
This means that HX is strongest acid followed by HY and then HZ.
