A 35 MGD surface Water treatement plant proposes to to use alum Coagulation for turbidity reduction using 44 mg/ L alum. the raw

water has an alkalinity of 80 mg / L as CaCO3. Commercial alum has the Formula Al2(SO4)3 X 18H2O (MW= 666).
A) determine the daily Alum Dosage Required in Kg/ day?

B) Using the Equivalent concept , how much alkalinity is used up by the alum added?

C) is the water alkalinity adequate. i.e , is it grater than the alkalinity consumed by alum?

Part A What are plate boundaries at which lithospheric plates that a) move toward each other, b) move past each other, and c) mo
Alex787 [66]

Answer:

a. Convergent boundary

b. Transform boundary

c. Divergent boundary

Explanation:

Convergent boundary are boundary where tectonic plates collide with each other. This kind of boundary might involve a collision between continental and oceanic plates, continental and continental plates and oceanic and oceanic plates. Generally, convergent boundary are regions for mountainous structures . Example of mountain formed through convergence are mountain Everest and Himalayas .

Transform boundary are boundary where tectonic plates move past each other . This kind of boundary is responsible for the creation of Extensive Fault like the San Andrea Fault.

Divergent boundary are boundary where tectonic plates move away from each other.  The diverging movements brings about oceanic ridges. The mid oceanic ridges is where magma rises to the surface to form a new crust. The up welling of this magma causes further separation of this plates.

The picture above illustrate convergent, divergent and transform boundary.

The compound adrenaline contains 56.7 % c, 6.56 % h, 28.37% o and 8.28 % n by mass. what is the empirical formula for adrenaline
-Dominant- [34]

Answer:- An empirical formula of adrenaline is C_8H_1_1O_3N .

Solution:- Convert given percentages to moles and then calculate the mol ratio to get the simplest whole number ratio of moles of atoms which is the empirical formula of the compound.

C=\frac{56.7}{12} = 4.725 mol

H=\frac{6.56}{1} = 6.56 mol

O=\frac{28.37}{16} = 1.773 mol

N=\frac{8.28}{14} = 0.591 mol

let's calculate the mol ratio now. To calculate the mole ratio, we divide the moles of each by moleso f N as it's the least one:

C=\frac{4.725}{0.591} = 8

H=\frac{6.56}{0.591} = 11

O=\frac{1.773}{0.591} = 3

N=\frac{0.591}{0.591} = 1

So, an empirical formula of adrenaline is C_8H_1_1O_3N .
