Answer:
Concentration of product at equilibrium ;
![[H^+]=0.0000229 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.0000229%20M)
![[CN^-]=0.0000229 M](https://tex.z-dn.net/?f=%5BCN%5E-%5D%3D0.0000229%20M)
Explanation:
![HCN(aq)\rightleftharpoons H^+(aq) + CN^-(aq)](https://tex.z-dn.net/?f=HCN%28aq%29%5Crightleftharpoons%20H%5E%2B%28aq%29%20%2B%20CN%5E-%28aq%29)
initially
0.85 M 0 0
(0.85-x)M x x
The equilibrium constant of reaction = ![K_c= 6.17\times 10^{-10}](https://tex.z-dn.net/?f=K_c%3D%206.17%5Ctimes%2010%5E%7B-10%7D)
The expression of an equilibrium cannot can be written as:
![K_c=\frac{[H^+][CN^-]}{[HCN]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH%5E%2B%5D%5BCN%5E-%5D%7D%7B%5BHCN%5D%7D)
![6.17\times 10^{-10}=\frac{x\times x}{(0.85-x)}](https://tex.z-dn.net/?f=6.17%5Ctimes%2010%5E%7B-10%7D%3D%5Cfrac%7Bx%5Ctimes%20x%7D%7B%280.85-x%29%7D)
Solving for x:
x = 0.0000229

Answer:
A) Fission
Explanation:
Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
It'll beginning to evaporate.
Answer:
1) The elements have filled valence levels.
Explanation:
Since they have filled valence levels, they're stable and don't need to electrons to fill their valence shells since they're already full.
2) False, They do have electrons
3) False, He does have only one electron shell, but going down the periods, every next element have one more electron shell than a preceding one has.
4)False, they're actually the smallest atoms of their respective period
Increase in Oxygen shift the equilibrium towards reactant side.
<u>Explanation:</u>
6CO₂ + 6H₂O ⇄ C₆H₁₂O₆ + 6O₂
This is the reaction occurs in the photosynthesis of plants by means of sunlight. In this case, if the concentration of Oxygen increases or adding more oxygen to the product side will shift the equilibrium towards the reactant side according to the Le Chatlier's principle, which adjusts the equilibrium by itself for any changes that is increase or decrease in pressure, temperature or concentration of reactants or products.
