Hey there!:
The fractional saturation y is defined as :
y = [ L ] / Kd + [ L ]
where :
[ L ] = concentration of binding ligand
Kd = 400 nm
Answer:- 2,1
Explanations:- Water is 
and from it's formula it is clear that the ratio of H to O moles or atoms is 2:1 means two hydrogen atoms for each oxygen atom. No matter what amount of water we have, the ratio of H atoms to O atoms is always same.
Hence, the answer is 2,1.
Answer:
Diazonium salts are salts formed from aromatic primary amines by diazotization. Diazonium salts are not very stable but very reactive. It therefore serves as a starting material for the preparation of various derivatives of arenes, azo dyes and pharmaceuticals.
There are two atoms of N.
Sound travels most quickly through solids because _____.
answer is: because solids r the most sense.
The distance between molecules in solids r very small.Because they are so close, they can collide very quickly, i.e. it takes less time for a molecule of the solid to 'bump' into its neighbor. Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids.
