I would say A
Explanation:
our ancestors are the people that lived long before us
Answer: -2.373 x 10^-24J/K(particles
Explanation: Entropy is defined as the degree of randomness of a system which is a function of the state of a system and depends on the number of the random microstates present.
The entropy change for a particle in a system depends on the initial and final states of a system and is given by Boltzmann equation as
S = k ln(W) .
where S =Entropy
K IS Boltzmann constant ==1.38 x 10 ^-23J/K
W is the number of microstates available to the system.
The change in entropy is given as
S2 -S1 = kln W2 - klnW1
dS = k ln (W2/W1)
where w1 and w2 are initial and final microstates
from the question, W2(final) = 0.842 x W1(initial), so:
= 1.38*10-23 ln (0.842)
=1.38*10-23 x -0.1719
= -2.373 x 10^-24J/K(particles)
The most common species of nitrogen in which its oxidation state is zero is the diatomic nitrogen (

). This is because the oxidation number of pure elements (whether alone as an atom or combined with other atoms of the same element such as the diatomic nitrogen) is always zero.
In addition to diatomic nitrogen, there are diazonium (

) compounds where nitrogen has an oxidation number of zero.
A=24
N(n)=13
N(p)=A-N(n)
N(p)=24-13=11
²⁴Na - sodium
atomic number is 11
Force = mass * acceleration
= 14 * 2 = 28N
Work done (energy) = Force * distance
= 28 * 5 = 140J
