<h3><u>Answer:</u></h3>

<u>1 mole of a gas at STP occupies 22.4 L volume </u>

<u>Now the volume is given =78.4 therefore,</u>

<u>No. of moles of gas = 78.4 ÷ 22.4 = 3.5 moles</u>

<u>I hope it helps you~</u>

What is the pH if the [H+] concentration is 3 x10^-13​
Shkiper50 [21]

Answer:

pH = 12.52

Explanation:

Given that,

The [H+] concentration is 3\times 10^{-13}.

We need to find its pH.

We know that, the definition of pH is as follows :

pH=-log[H^+]

Put all the values,

pH=-log[3\times 10^{-13}]\\\\pH=12.52

So, the pH is 12.52.

consider this reaction at equilibrium at a total pressure: 2h2o(g) o2(g) 2h2o2(g) suppose the volume of this system is twice its
Daniel [21]

The total pressure when the new equilibrium is stabilized is half of the initial pressure of the system.

The given chemical reaction at a stable equilibrium is,

2H₂O(g)+O₂(g) = 2H₂O₂(g)

According to the ideal gas equation,

PV = nRT

P is pressure,

V is volume,

n is moles

R is gas constant,

T is temperature.

Assuming the temperature is constant.

If the volume of the system is twice the initial volume then the total pressure at the new equilibrium can be found out as,

P₁V₁ = P₂V₂

Where, P₁ and V₁ are initial volume and pressure while P₂ and V₂ are final pressure and volume.

If V₂ = 2V₁,

P₂ = P₁/2

So, the final total pressure will be half of the initial pressure.
