Based on the bond energies given for each of the following which is the most stable? 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

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.

The greater the bond energy, the greater is the amount of energy required to break the bond, the more stable is the bond.

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

The greatest bond energy is of N≡N 946 kJ/mol and thats why it is the most stable.

Explanation:

yup

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
