Explicación:
Todo este proceso se conoce como oximercuración y demercuración.
El primer paso es la mercuración y el siguiente paso es la demercuración.
Se trata de una reacción de adición electrofílica y generalmente se utiliza agua como disolvente, pero aquí se proporciona metanol, así que en lugar de que el agua ataque, será el metanol quien lo haga.
En esta reacción, el alceno reacciona primero con acetato de mercurio (AcO–Hg–OAc)
y forma un anillo con el alceno, ya que el electrón pi del alceno se comparte con el acetato de mercurio y no se forma carbocation, por lo tanto no habrá lugar para reestructuraciones.

Explanation:
Tritium undergoes a first-order decay represented by the following relation.
![ln(\frac{[H]_{t}}{[H]_{0}} )=-k.t](https://tex.z-dn.net/?f=ln%28%5Cfrac%7B%5BH%5D_%7Bt%7D%7D%7B%5BH%5D_%7B0%7D%7D%20%29%3D-k.t)
where,
[H]t denotes the tritium concentration at a specific time t
[[H]₀ signifies the initial concentration of tritium
k represents the rate constant
Knowing the half-life (t1/2), we can compute the rate constant.
![ln(\frac{[H]_{t}}{[H]_{0}} )=-k.t\\ln(\frac{0.34[H]_{0}}{[H]_{0}} )=-(0.0564y^{-1}).t\\t=19y](https://tex.z-dn.net/?f=ln%28%5Cfrac%7B%5BH%5D_%7Bt%7D%7D%7B%5BH%5D_%7B0%7D%7D%20%29%3D-k.t%5C%5Cln%28%5Cfrac%7B0.34%5BH%5D_%7B0%7D%7D%7B%5BH%5D_%7B0%7D%7D%20%29%3D-%280.0564y%5E%7B-1%7D%29.t%5C%5Ct%3D19y)
Answer:
The result is 4
Explanation:
You calculate the density by dividing the mass by the volume.
For instance, 19.2 divided by 4.8 equals 4.
Answer:
The reaction rate, R= 
Explanation:
Based on the Rate Law:
R=k[O3][NO]
Here, the order for NO is 1 and for O3 is also 1,[ [TAG_15]]
Thus, the total order of reaction =1+1=2
Given:
Concentration of O3 = [03]= 3.0×10^-4M
Concentration of NO= [NO]= 8.0×10^-5M
Rate constant K=3.0×10^6M^-1s^-1
Substituting the given values into the rate law equation
R= 3.0×10^6 × 3.0×10^-4 ×
8.0×10^-5
R= 0.072
Thus, the reaction rate is 0.072
Answer:
Iron-56 is the predominant isotope, making the atomic mass of iron closest to that of iron-56.
Explanation:
The isotopic abundance for iron is:
⁵⁴Fe: 5.82%
⁵⁶Fe: 91.66%
⁵⁷Fe: 2.19%
⁵⁸Fe: 0.33%
This indicates that Iron-56 is the most prevalent isotope of iron.
Considering that the atomic mass is derived from the sum of the masses of the isotopes adjusted for their abundance, and given that Iron-56 is the most common isotope, it follows that the atomic mass of Fe is likely to be similar to that of ⁵⁶Fe due to its higher abundance.
The accurate option is:
Iron-56 is the primary isotope, hence the atomic mass of iron aligns closely with the mass of iron-56.
