first know the difference between the 4 seasons or weather's that occur and that will help get through
The answer is 42 neutrons
The enthalpy of the reaction is the amount of energy absorbed or lost in the reaction. The enthalpy of the final reaction is -113.4 kJ.
<h3>What are intermediate reactions?</h3>
The intermediate reactions are the small reactions that takes place in order to achieve the final reaction product.
The given intermediate reactions are:
The final reaction to be achieved is:
The second reaction is reversed in order to achieve the final reaction product.
The enthalpy of the final reaction (
) is given as:
Substituting the values of enthalpy:
The final enthalpy of the reaction is -113.4 kJ. Thus, option B is correct.

Answer:
True
It is true that he size of coupling constants (J values) depend on three factors:
a. Through bond distance between the protons.
b. Angle between the two C-H bonds.
c. Electronegative substituents.
Explanation:
With the increase in the valence angle the coupling constant reduces. The distance between the carbon atoms also influence coupling constant. With increase in bond length, the coupling constant decreases. Also the more an atom is electronegative, the lesser is the coupling constant
Thus, it is true that he size of coupling constants (J values) depend on three factors:
a. Through bond distance between the protons.
b. Angle between the two C-H bonds.
c. Electronegative substituents.
Answer:
16. What is the wavelength of a 1.32 x 10-6 eV wave?
ν = E /ν = h = 1.32 x 10-6
eV x 1.602 x 10-19
J = 3.191 331 38 x 10+8 s-1
6.626 2 x 10-34J-s 1 eV
λ = c/ν = ν = 3.00 x 108
m/ν = s = 3.00 x 108
m x 1
3.191 331 38 x 10+8 s-1
s 3.191 331 38 x 10+8 s-1
= 0.940 m
Explanation:
The answer is 0.940 m That is unless i messed something up-
