<h2>Nitrogen fixation </h2>
Explanation:
It is the process of converting free nitrogen into nitrogenous compounds .
Let us study about it :
In nature there are certain plants called as leguminous plants .These plants have nitrogen fixing bacteria called as rhizobium in their root nodules .
This bacteria can convert free atmospheric nitrogen into ammonia .
Then this ammonia with the help of bacteria nitrosomonas and nitrobacter gets converted into nitrites and nitrates .
Then these nitrites and nitrates with the help of bacteria like pseudomonas gets converted back into free nitrogen ,
This cycle helps in enriching the soil and to maintain nitrogen percent constant in atmosphere ,
The biogeochemical cycle : for nitrogen is attached below
Answer:
KOH
Explanation:
Chemical reaction:
2K + 2H₂O → 2KOH + H₂
Element ratio of K.
K = 1
Because only potassium is present.
Element ratio of H₂O.
2 : 1
in water ratio of element is 2 : 1 because two hydrogen and one oxygen atom present.
Element ratio of KOH
1 : 1 : 1
in KOH elemental ratio is 1 : 1 : 1 because one potassium one hydrogen and one oxygen atom are present.
Element ratio of H₂.
2
Just two atoms of hydrogen are present.
Not sure about the number of significant figures; you can decide where to round, but I would probably say 0.075mol.
The answer would be uranium and thorium. When an alpha ejects a particle, it will create a new atom. So, when uranium ejects an alpha particle, it will produce thorium. They call this process as the alpha decay. Alpha decay often happens on atoms that are abundant nuclei such as uranium, radium, and thorium.
