The diagram below shows the collection of H2 gas over water at 25°C. The total pressure in the tube is 760.0 torr. What is the p

ressure exerted by the hydrogen gas alone? (Hint: water vapor pressure = 23.8 torr @ 25°C)

Answer: 736.2 torr

Explanation: According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

p_{total}=p_A+p_B

Thus p_{total}=p_{H_2O}+p_{H_2}

Given: p_{total}=760 torr

p_{H_2O}=23.8torr

p_{H_2}= ?torr

Thus 760torr=23.8torr+p_{H_2}

p_{H_2}=736.2torr

Thus pressure exerted by the hydrogen gas alone is 736.2 torr.

In a mixture of He, Ne, and Kr the total pressure is 125 kPa. The partial
tatiyna

Answer:

Partial pressure of He = 73 kPa

Explanation:

Given:

Total pressure = 125 kPa

Partial  pressure of Ne = 31 kPa

Partial pressure of Kr = 21 kPa

Find:

Partial pressure of He

Computation:

Total pressure = Partial  pressure of Ne + Partial  pressure of Kr + Partial  pressure of He

125 kPa = 31 kPa + 21 kPa + Partial pressure of He

Partial pressure of He = 73 kPa

9. According to an "alternative theory", H2O is
Jlenok [28]

Answer:(4) ----accepts  a proton

Explanation:

H2O water can produce both hydrogen and   hydroxide ions

H2O --> H+ + OH-

According to the Bronsted-Lowry theory, it can be a proton donor and a proton acceptor.this means that It can donate a hydrogen ion to become its conjugate base, or  can accept a hydrogen ion to form its conjugate acid,

When , a water molecule, H2O accepts a proton it will act as a Brønsted-Lowry base especially when dissolved in a strong acidic medium. for eg

HCl + H2O(l) → H3O+(aq) + Cl−(aq)

Here, Hydrochloric acid is a strong acid and ionizes completely in  water, since it is more acidic than water, the water will act as a base.
