Calculate the final molarity of H2O2 if 5.5 mL of a 3.0% w/w H2O2 solution, which has a density of 1.0 g/mL, is added to 5.5 mL
1 answer:
We have that the final molarity of H2O2 if 5.5 mL of a 3.0% w/w H2O2 solution, which has a density of 1.0 g/mL, is added to 5.5 mL of a starch-iodide solution. is
From the question we are told
Calculate the final molarity of H2O2 if 5.5 mL of a 3.0% w/w H2O2 solution, which has a density of 1.0 g/mL, is added to 5.5 mL of a starch-iodide solution.

<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
