A mixture of three noble gases has a total pressure of 1.25 atm. The individual pressures exerted by neon and argon are 0.68 atm

and 0.35 atm, respectively. What is the partial pressure of the third gas, helium? Use mc031-1.jpg. 0.22 atm 0.33 atm 1.03 atm 2.28 atm

<u>Given information:</u>

Gas mixture containing: Ne + Ar + He

Total pressure P = 1.25 atm

Partial pressure pNe = 0.68 atm

pAr = 0.35 atm

<u>To determine:</u>

Partial pressure of He i.e. pHe

<u>Explanation:</u>

As per Dalton's law, the total pressure of a gas mixture is equal to the sum of partial pressure of the gases

P = pNe + pAr + pHe

pHe = P - (pNe+pAr) = 1.25 - (0.68 + 0.35) = 0.22 atm

<u>Answer:</u>

Partial pressure of He is 0.22 atm

Add the Pressure of neon and argon that is 0.68 +0.35= 1.03
Total pressure that is 1.25 -1.03=0.22 atm

Write an equation that represents the action in water of rubidium hydroxide as an Arrhenius base.
Anika [276]

Answer:

RbOH  → Rb⁺ +  OH⁻

As the hydroxide can gives the OH⁻ in water, it is considered as an Arrhenius's base

Explanation:

Arrhenius theory states that a compound is considered a base, if the compound can generate OH⁻ ions in aqueous solution.

Our compound is the RbOH.

When it is put in water, i can dissociate like this:

RbOH  → Rb⁺ +  OH⁻

As the hydroxide can gives the OH⁻ in water, it is considered as an Arrhenius's base

Use the specific heat capacity that you calculated for granite to determine how many grams of granite at the initial temperature
Valentin [98]

Answer:

Explanation:

specific heat of granite s = .79 J / g / k

let the mass of granite = m

heat lost by granite = heat gained by water

heat lost = mass x specific heat x drop in temperature

= m x .79 x (80 - 20.45)

heat gained by water

= 3000 x 4.186 x (20.45- 20)

heat lost by granite = heat gained by water

m x .79 x 59.55  =  3000 x 4.186 x .45

m = 120.12 g .

What minimum concentration of k2co3 is required to cause the precipitation of the cation that precipitates first?
Lady_Fox [76]

Answer:

The concentration is ion dependent

Explanation:

The concentration is dependent on the amount of the ions in the solution. This is the rate-determination factor. For a reaction to precipitate, there should be enough ions in the solution.  In addition, the Ksp plays an important factor in the reaction. This happens when the amount of ions formed is derived from a strong ionic solution. This then drives the reaction forward.
