It takes <u><em>about a month</em></u> for the Moon to complete one revolution around the earth. It is much longer than 60 hours and much shorter than 365 days. <u><em>So the correct answer is C. 29.5 days. I think you made a typo, because the correct answer is 29.5 days not years.</em></u>

Explanation:</h3>
Nickel is the transitional metal in the compound
The overall charge of the compound Ni₃P
= the sum of the charges of element × the number number of atoms
<em />
<em>Because Ni₃P is a neutral compound, then the overall charge of the compound is zero.</em>
⇒ 3 (charge of Ni) + (charge of P) = 0
⇒ 3 (charge of Ni) = - (charge of P) <em> [Redox Rules: Group 15 </em>
<em> elements of -3.]</em>
⇒ 3 (charge of Ni) = - (-3)
(charge of Ni) = + 1
Answer:
2.16 MeV
Explanation:
To determine the amount of work done that is needed to assemble the atomic mass; we need to apply the equation;
U =
where:
= proportionality constant =
e = magnitude of the charge of each electron =
r = length of each side of the vertex =
So; replacing our values into above equation; we have:
U =
U = 3.456 × 10 ⁻¹³ J
If we have to convert our unit from J to Mev; then we are going to have:
U = 3.456 × 10 ⁻¹³ J
U = 2.16 MeV
Therefore, the amount of work done needed to assemble an atomic nucleus = 2.16 MeV
