(4.5 x 10^24)/(6.02 x 10^23) = 7.475 mol O :)
Concentrated phosphoric acid is added to the reaction mixture in the synthesis of aspirin to maintain the acidic environment and to keep the reagents protonated.
<h3>What is the phosphoric acid?</h3>
Phosphoric acid is an inorganic acid with the molecular H₃PO₄.
Its a triprotic acid which means that one molecule of the acid produces 3 molecules of hydrogen ions.
Phosphoric acid is important for many laboratory as well as industrial uses. It can be serve as buffer in living organisms.
It also used in the synthesis of aspirin.
The synthesis of aspirin requires an acidic environment. Therefore, concentrated phosphoric acid is added to the reaction mixture in the synthesis of aspirin to maintain the acidic environment and to keep the reagents protonated.
In conclusion, Phosphoric acid ensures an acidic environment in the synthesis of aspirin.

Answer: :)
Ore is commonly found and formed in rocks under the ocean floor and beneath the ground.
Explanation:
:/
Answer:
V₂ = 317 L
Explanation:
Given data:
Initial number of moles of hydrogen = 18.9 mol
Initial volume of gas = 428 L
Final volume = ?
Final number of moles = 14.0 mol
Solution:
According to the Avogadro law,
Number of moles of gas is directly proportional to the volume of gas at constant temperature and pressure.
Mathematical expression:
V₁/n₁ = V₂/n₂
V₁ = Initial Volume of balloon
n₁ = initial number of moles
V₂ = Final volume of balloon
n₂ = Final number of moles
Now we will put the values.
428 L / 18.9 mol = V₂/ 14 mol
V₂ =428 L × 14 mol / 18.9 mol
V₂ = 5992 L /18.9
V₂ = 317 L
The body uses energy to break chemical bond(takes energy). When a bond forms, energy is released(like magnet) in the form of Kinetic Energy. Bonds are being broken & formed in your body at the same time(series of chemical reactions).
