Answer:
1.1 M
Explanation:
The dissociation of is as follows:
Given Value for
The equation for the reaction for the formation of complex ion is :
The value of
If we combine both equation and find the overall equilibrium constant will be:
<u> </u>
If = x M
The solubility of in the solution will be:
Constructing an ICE Table; we have :
Initial (M) x 0 0
Change (M) -2 (0.0518) + 0.0518 + 0.0518
Equilibrium (M) x - 0.1156 0.0518 0.0518
Equilibrium constant;
(K) =
x = [NH₃] = 1.089 M
[NH₃] ≅ 1.1 M
Answer: Photosynthetic organisms take light energy and use it to make their own "food". In this process they use carbon dioxide and light to make sugars and oxygen. This is great for other animals that utilize this oxygen and eat the plants for food.

Answer:
c. H₂O (l) → H₂O(s)
Explanation:
The correct answer is option C: The molecular formulas for the substance(s) on the left side of the equation and on the right side of the equation are identical. This means that there was not a chemical change, but a physical one.
In this concrete example, what happened was a <em>change of states of matter</em>: from liquid (l) to solid (s).
Other reactions have different molecular formulas on both sides of the equation, thus they represent chemical changes.
