A
Bronsted-Lowry acid is a proton donor (usually hydrogen ion). And a
Bronsted-Lowry base is a proton acceptor (usually hydrogen ion). Consider a
chemical reaction between HCl and NaOH. We have the reaction HCl + NaOH à NaCl + H2O. The
hydroxide ions in the NaOH are bases because they accept hydrogen ions from
acids to form water. And an acid produces hydrogen ions in solution by giving a
proton to the water molecule. Therefore, the answer is d. a Bronsted-Lowry
base.
Answer:
P(total) = 15 atm
Explanation:
Given data:
Pressure of O₂ = 5.75 atm
Pressure of N₂ = 7 atm
Pressure of He = 2.25 atm
Total pressure inside tank = ?
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Now we will solve this problem by using this law.
P(total) = P(O₂) + P(N₂) + P(He)
P(total) = 5.75 atm + 7 atm + 2.25 atm
P(total) = 15 atm
