The pressure that  will  be   exerted if  four sample  of gas are placed in a single  3.5 container  is calculated as below

if  each gas occupies 675  mmhg

what about  4 gases in the sample
by cross  multiplication

= 675 mm hg x 4/1 = 2.7  x10^3mmhg (answer D)

What volume (in L) of oxygen will be required to produce 77.4 L of water vapor in the reaction below?
Inga [223]

Answer:

90.3 L

Explanation:

Given data:

Volume of water produced = 77.4 L

Volume of oxygen required = ?

Solution:

Chemical equation:

2C₂H₆ + 7O₂  →  4CO₂ + 6H₂O

It is known that,

1 mole = 22.414 L

There are 7 moles of oxygen = 7×22.414 = 156.9 L

There are 6 moles of water = 6×22.414 = 134.5 L

Now we will compare:

                               H₂O           :              O₂    

                               134.5         :              156.9

                                 77.4         :             156.9/134.5×77.4 =90.3 L

So for the production of 77.4 L water 90.3 L oxygen is required.

elixir [45]

Answer- The intermingling of atoms takes place the help of diffusion.

Explanation- There are two areas one has a higher concentration and the other has a lower concentration and a substance moves from higher to lower and the process happening is called diffusion.

Combustion is heating up of the substance hence does not have any intermingling atoms and energy transport also does not have any atoms mingling together hence diffusion is the correct option.
