A gas with a vapor density greater than that of air, would be most effectively displaced out off a vessel by ventilation.

The two following principles determine the type of ventilation: Considering the impact of the contaminant's vapour density and either positive or negative pressure is applied.

Consider a vertical tank that is filled with methane gas. Methane would leak out if we opened the top hatch since its vapour density is far lower than that of air. A second opening could be built at the bottom to greatly increase the process' efficiency.

A faster atmospheric turnover would follow from air being pulled in via the bottom while the methane was vented out the top. The rate of natural ventilation will increase with the difference in vapour density. Numerous gases that require ventilation are either present in fairly low concentrations or have vapor densities close to one.

Answer:

5.60 Liters at STP

Explanation:

First you need the balanced reaction equation

2 H2 +  O2   ====>   2  H2O

4 g of oxygen ( O<u>2</u> )  is   4/(15.999*2) moles of O2     (using periodic table)

  Twice the number of moles of H2O re produced   (from equation)

     at STP the volume of a mole of gas is 22.4 liter/ mole

       put all of this together  

         2 *   4 / (15.999*2) moles * 22.4 L/mole = 5.60 L

Calculate the pH of a solution with an H+ ion concentration of 9.36 x 10-3 M ?
mel-nik [20]

Answer:

The answer is 2.03

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

where H+ is the Hydrogen ion concentration

From the question we have

pH =  -  log(9.36 \times  {10}^{ - 3} )  \\  = 2.02872415...

We have the final answer as

<h3>2.03 </h3>

Hope this helps you
