An environmental scientist studies the environment - you can see that in the beginning of the sentence :)
Answer:
0.1 is the retention factor.
Explanation:
Distance covered by solvent ,
Distance covered by solute or ion,
Retention factor
is defined as ratio of distance traveled by solute to the distance traveled by solvent.


0.1 is the retention factor.
Answer: AgCl
Explanation:
When the reaction takes place in which the sodium chloride is reacted with silver nitrate then the products formed are sodium nitrate and silver chloride.
NaCl(aq) + AgNO3(aq) ⟶ NaNO3(aq) + AgCl (s)
This reaction is known as precipitation reaction in which the white precipitate of silver chloride is formed.
This precipitate is insoluble and separates out of the solution.
So, the correction answer is AgCl(silver chloride).
I think it would be
Carbon + 2 Hydrogen= Carbon + Hydrogen + Carbon + 3 Hydrogen + 2 Bromine
But I’m not really sure, sorry if I’m wrong
Hope this helped
