Answer:
The cost and size of materials needed to produce energy
Explanation:
Artificial photosynthesis is a chemical process that uses solar cells instead of chlorophyll to absorb sunlight and convert it into electricity. This process uses artificial leaves that require man-made catalyst to spilt water present in the air into hydrogen and oxygen. It is clear that the reaction requires heat from the sun for energy production thus the technology is expensive to be applied in most areas of the world. Additionally, results obtained from previous undertaken projects of this type has been ineffective and unsustainable because it involves a lot of trial and error.

can u tell me the definition tho?
palled correctly as “though” which is an alternate form of “although”) at the end is informal usage. It's better placed before “she seems better today
Answer:
Explanation:
Given data:
Ammonia Nitrogen 30 mg/L
pH = 8.5
-log[H +] = 8.5
[H +] = 10^{-8.5}
Rate constant is given as
![K_a = \frac{[H^{+}] [NH_3]}{NH_4^{+}}](https://tex.z-dn.net/?f=K_a%20%3D%20%5Cfrac%7B%5BH%5E%7B%2B%7D%5D%20%5BNH_3%5D%7D%7BNH_4%5E%7B%2B%7D%7D)
...........1
Total ammonia as NItrogen is given as 30 mg/l
![\%NH_4^{+} = \frac{ [NH_4] \times 100}{[NH_4^{+}] + [NH_3]}](https://tex.z-dn.net/?f=%5C%25NH_4%5E%7B%2B%7D%20%3D%20%5Cfrac%7B%20%5BNH_4%5D%20%5Ctimes%20100%7D%7B%5BNH_4%5E%7B%2B%7D%5D%20%2B%20%5BNH_3%5D%7D)
= 
.....2
from equation 1 we have
![\frac{NH_3^+}{NH_4^+} =\frac{K_a}{[H^+]} = \frac{5.6\times 10^{-10}}](https://tex.z-dn.net/?f=%5Cfrac%7BNH_3%5E%2B%7D%7BNH_4%5E%2B%7D%20%3D%5Cfrac%7BK_a%7D%7B%5BH%5E%2B%5D%7D%20%3D%20%5Cfrac%7B5.6%5Ctimes%2010%5E%7B-10%7D%7D)
{10^{8.5}}
plug this value in equation 2 we get
Total ammonia as N = 30 mg/lt
