Solution :
According to Chick's law
where, t = contact time
c = concentration of disinfectant
k' = lethality coefficient = 4.71
n = dilution coefficient = 1
4 log removal = % removal = 99.99
= 1 - R
= 1 - 0.9999
Now for plug flow reactor contact time,
= 0.01875 days
= 27 minutes
For CSTR, 
days
= 5.4 minute
There are 3 reactors, hence total contact time = 3 x 5.4
= 16.2 minute
Or
or 
∴ C x t = 1.955
For PFR, 
min
∴ C 
= 0.072 mg/L
For CSIR, 
min
mg/L
∴ Chlorine required for PFR in kg/day
(1 gallon = 3.785 L)
= 18.25 kg/day
Therefore we should go for PFR system.
Answer: Directly through the phospholipid membrane
Explanation:
The cell membrane consist of a phospholipid bilayers structure. In the interior of the membrane, the phospholipid tail are hydrophobic, which makes the cell membrane to be selectively permeable, it is permeable to non polar molecules and impermeable to polar molecules.
Because Steroids are fat soluble, non polar compounds, they can diffuse directly through the hydrophobic, non polar core of the phospholipid bilayer without the use of carrier proteins.
Answer:
red because of how reflective and hydrogen
Explanation:
Lithium sulfate is Li2SO4
Strontium chlorate is Sr(ClO3)2
Strontium sulfate is SrSO4
So the complete balanced chemical reaction for this is:
Li2SO4 (aq) + Sr(ClO3)2
(aq) --> SrSO4 (s) + 2 LiClO3
(aq)
This is a type of double replacement reaction since there
is an exchange of ions.
