There are two main ways nitrogen can become "fixed:"
Fixation by lightning: The energy from lightning causes nitrogen (N2) and water (H2O) to combine to form ammonia (NH3) and nitrates (NO3). Precipitation carries the ammonia and nitrates to the ground, where they can be assimilated by plants.
Biological fixation: About 90% of nitrogen fixation is done by bacteria. Cyanobacteria convert nitrogen into ammonia and ammonium: N2 + 3 H2 → 2 NH3. Ammonia can then be used by plants directly. Ammonia and ammonium may be further reacted in the nitrification process.
Explanation:
CBr4 is larger than CH4, so it has a higher London dispersion, A type of Intermolecular force. Higher force means longer time to
bring the substance to boil,Meaning a higher boil point
The type of reaction of Fe2O3 + 2SiO2 → Fe2Si2O7 would be that it is a synthesis reaction. It <span>is a type of chemical </span>reaction<span> in which two or more simple substances combine to form a more complex product. Hope this answers the question. </span>
Answer:
49.1 g
Explanation:
First we <u>convert 9.67x10²³ atoms of oxygen into moles</u>, using <em>Avogadro's number</em>:
- 9.67x10²³ atoms ÷ 6.023x10²³ atoms/mol = 1.60 mol O
Then we <u>calculate how many P₃O₉ moles there would be with 1.60 O moles</u>:
- 1.60 mol O * = 0.18 mol P₃O₉
Finally we convert 0.18 P₃O₉ moles into grams, using its molar mass:
- 0.18 mol P₃O₉ * 237 g/mol = 49.1 g
The solution would be like
this for this specific problem:
<span>1.0
</span>atm + 2.0 atm
+ 3.0 atm = 6.0 atm
So the partial pressure of
the helium 3.0 atm.
