If you are allowing plants to decompose when dead that will add nitrogen to the ecosystem. Plants need nitrogen for photosynthesis. Decomposition and carbon dioxide provide carbon. They expel oxygen. I would say they provide all between dying (decomposition) and respiration.

State relationship between the level of dissolved oxygen and water temperature
Artemon [7]
More dissolved oxygen is present in water with a lower temperature compared to water with a higher temperature. The reason for this inverse relationship between dissolved oxygen and temperature is that the solubility of a gas in a liquid is an equilibrium phenomenon.

Using the appropriate ksp value from appendix d in the textbook, calculate the ph of a saturated solution of ca(oh)2 .
Alex777 [14]
The ph of a saturated solution of Ca(OH)2 is 12.35

CALCULATION:
For the reaction 
     Ca(OH)2 → Ca2+ + 2OH- 
we will use the Ksp expression to solve for the concentration [OH-] and then use the acid base concepts to get the pH:
     Ksp = [Ca2+][OH-]^2

The listed Ksp value is 5.5 x 10^-6. Substituting this to the Ksp expression, we have
     Ksp = 5.5 x 10^-6 = (s) (2s)^2 = 4s^3
     s3 = 5.5x10^-6 / 4

Taking the cube root, we now have
     s = cube root of (5.5x10^-6 / 4)s
        = 0.01112

We know that the value of [OH-] is actually equal to 2s:
     [OH-] = 2s = 2 * 0.01112 = 0.02224 M

We can now calculate for pOH:          
     pOH = - log [OH-]
              = -log(0.02224)
              = 1.65

Therefore, the pH is
     pH = 14 - pOH
           = 14 - 1.65
           = 12.35

Laws of conservation of mass/pleases help
umka2103 [35]

Answer:

27g + 33g = 60g

18g + 24g = 42g

Explanation:

The law of conservation of mass states that no matter can be destroyed or created.  Because of this, you are simply making both sides equal.
