Explanation:
The given data is as follows.
Moles of oxygen gas = 0.150 mol, Moles of nitrogen gas = 0.116 mol
Moles of argon gas = 0.211 mol, Volume of the flask = 0.5 L
Temperature = 298 K
So, total number of moles will be calculated as follows.
= (0.150 + 0.116 + 0.211) mol
= 0.477 mol
Now, using ideal gas equation we will calculate the total pressure of given gas mixture as follows.
PV = nRT
P = 23.34 atm
Mole fraction of gas will be calculated as follows.
Mole fraction =
=
= 0.243
Using Dalton's law,
where, = partial pressure of a gas
= total pressure
= mole fraction of gas
Therefore, putting the values into Dalton's law to calculate the partial pressure of nitrogen gas as follows.
=
= 5.67 atm
Thus, we can conclude that the partial pressure of into the given mixture is 5.67 atm.
Answer:
Diffusion of Innovation (DOI) Theory, developed by E.M. Rogers in 1962, is one of the oldest social science theories. It originated in communication to explain how, over time, an idea or product gains momentum and diffuses (or spreads) through a specific population or social system
Explanation:
steps of divusion if you need it are
Knowledge. The first step in the diffusion of innovation is knowledge. ...
Persuasion. Persuasion is the point at which the prospective adopter is open to the idea of purchase. ...
Decision. Eventually the would-be adopter must make a decision. ...
Implementation. ...
Confirmation.
Happy to help;)!
Explanation:
When we have direct sunlight, the temperature is higher compared to indirect sunlight.
Direct sunlight is usually overhead whereas indirect sunlight is at an angle to the surface.
- Direct sunlight impacts the surface with more energy concentrated on a smaller surface area.
- This warms the surface more.
- Indirect sunlight is diffuse and spreads over a wider area.
- This leads to a reduction in temperature.
