Answer : The equilibrium constant for this reaction is, 
Explanation :
The given main chemical reaction is:
; 
The intermediate reactions are:
(1)
; 
(2)
; 
We are reversing reaction 1 and multiplying reaction 2 by 2 and then adding both reaction, we get:
(1)
; 
(2)
; 
Thus, the equilibrium constant for this reaction will be:


Thus, the equilibrium constant for this reaction is, 
11 electrons , 11 protons , 12 neutrons.
Explanation:
When a soil lacks earthworm, it will be poorly aerated and organic matter will be lacking.
Earthworms burrow through the soil and leaves holes and pores around in the soil.
- Soil air is an important component that makes up the soil.
- Earthworm are good burrowers that penetrates the soil and creates pores.
- This facilitate infiltration of water into the soil and also the circulation of air.
- Also, since they are decomposers, they the leave the soil rich and filled with organic matter.
