Considering the Dalton's law, the total pressure of the tank is 5.95 atm.
<h3>Dalton's law</h3>
The pressure exerted by a particular gas in a mixture is known as its partial pressure.
So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:
where n is the amount of gases present in the mixture.
This relationship is due to the assumption that there are no attractive forces between the gases.
<h3>Total pressure of the tank</h3>
A tank of gas has partial pressures of nitrogen and oxygen equal to 1.61 atm and 4.34 atm, respectively.
The total pressure of the tank is calculated as:
So, replacing the respective values:
Solving:
Finally, the total pressure of the tank is 5.95 atm.

Answer:
(a). Biological fixation
(b). Fixation by lightning
Explanation:
Gaseous nitrogen in the atmosphere has to be converted or "fixed" into a suitable form before it can be utilised by living organisms.
There two main ways of nitrogen fixation are
(a). Biological fixation: Majority (approximately 90%) of nitrogen fixation is carried out by bacteria. Bacterias such as Cyanobacteria transforms nitrogen into ammonium and ammonia : N2 + 3 H2 → 2 NH3. The produced ammonia can then be taken in directly by plants and /or the conversion products of ammonium and ammonia may further react in the process of nitrification.
(b). Fixation by lightning: Lightning energy causes the combination nitrogen (N2) and water (H2O) forming nitrates (NO3) and ammonia (NH3) . Rain water dissolves the formed nitrates and ammonia and the solution is drained into the ground, where they can be reached by plants plant roots for consumption.
Answer:
A.
Explanation:
specific heat of water is immense as compared to most of other known substances. The result of this characteristic is that water heats slowly and cools slowly. In coastal region and islands, the air above lands gets heated up quickly as compared to air above water.
Gravity because the earth's gravity is what's causing it to orbit it
I looked it up and i saw tht it was ions and electrons.
hope this helps you!! :)
