Answer:
N≡N bond
Explanation:
Bond energy (bond enthalpy) is a measure of the bond strength in the bond. It is defined as average value of bond dissociation energies in the gas-phase for all the bonds having same type with in same chemical species.
<u>The greater the bond energy, the greater is the amount of energy required to break the bond, the more stable is the bond.</u>
Thus, among the following bonds:
O=O 498 kJ/mol
N≡N 946 kJ/mol
C=C 614 kJ/mol
C=O 745 kJ/mol
C≡C 839 kJ/mol
<u>The greatest bond energy is of N≡N 946 kJ/mol and thats why it is the most stable.</u>
Answer:
The particle which completes the given equation is :
Explanation:
The given reaction is of a fission reaction:

Total mass on the reactant side is equal to the total mass on the product side:
239 + 1 = 100 +A+ 2
A = 138
Sum of atomic numbers on the reactant side is equal to the sum of atomic number on the product side:
94 + 1(0) = 40 + Z + 2(0)
Z = 54
So atomic number 54 id of Xenon.
The particle which completes the given equation is :

In the first figure, the surface absorbs all colors except for green light, which is reflected: so, the surface will appear as green to our eyes, because green is the only color which is reflected by that surface.
Similarly, in the second figure, the surface absorbs all colors except for blue, and so the surface will appear blue to our eyes.
In the third figure, the surface absorbs all colors, so it will appear black to our eyes (because no colors are reflected, and black=absence of colors).
In the fourth figure, all colors are reflected: this means the surface will appear white to our eyes (white= sum of all colors).
Answer:
This is a paradox — an inconsistency that often leads people to think that time travel cannot occur in our universe." A variation is known as the "grandfather paradox" — in which a time traveler kills their own grandfather, in the process preventing the time traveler's birth
