27. Sample of neon gas has a pressure of 4.1 atm and argon gas with a pressure of 3.2 atm are added to a
MrRa [10]

Answer:

Option C. 13.5 atm

Explanation:

From the question given above, the following data were obtained:

Pressure of Neon (Pₙₑ) = 4.1 atm

Pressure of Argon (Pₐᵣ) = 3.2 atm

Pressure of nitrogen (Pₙ₂) = 6.2 atm

Total pressure (Pₜ) =?

The total pressure in the container can be obtained by adding the pressure of the individual gases. This is illustrated below:

Pₜ = Pₙₑ + Pₐᵣ + Pₙ₂

Pₜ = 4.1 + 3.2 + 6.2

Pₜ = 13.5 atm

Therefore, the total pressure in the container is 13.5 atm

What is the concentration of H+ ions at a pH = 2?
erastova [34]

Answer:

0.01M = [H⁺]; 1x10⁻¹²M = [OH⁻]; Ratio is: 1x10¹⁰

Explanation:

pH is defined as -log [H⁺]

For a pH of 2 we can solve [H⁺] as follows:

pH = -log [H⁺]

2 = -log [H⁺]

10^-2 = [H⁺]

<h3>0.01M = [H⁺]</h3>

Using Keq of water:

Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]

1x10⁻¹⁴ / 0.01M = [OH⁻]

<h3>1x10⁻¹²M = [OH⁻]</h3><h3 />

The ratio is:

[H⁺] / [OH⁻] = 0.01 / 1x10⁻¹² =

<h3>1x10¹⁰</h3>
