When Americium (Am-241) undergoes alpha decay(He-4) it forms neptunium (Np-237) based on the following pathway:
²⁴¹Am₉₅ → ²³⁷Np₉₃ + ⁴He₂
The energy released in given as:
ΔE = Δmc²
where Δm = mass of products - mass of reactants
= [m(Np-237) + m(He-4)] - [m(Am-241)]
= 237.0482+4.0015-241.0568 = -0.0073 g/mol = -7.3 * 10⁻⁶ kg/mol
ΔE = -7.3*10⁻⁶ kg/mol * (3*10⁸ m/s)² = -5.84*10¹¹ J/mol

The earth’s rotation
Answer:
The gravitational pull from the moon and sun
Explanation:
Answer: gravity
Explanation:
Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).
Answer:
C) plasma
Explanation:
Plasma is the state where electrons are stripped allow these gases to conduct electricity.
The principal reason why we must consider the uncertainty principle when discussing electrons and other subatomic particles but not when discussing our macroscopic world is:
According to the given question, we need to state the principal reason why the uncertainty principle is used when discussing electrons and other subatomic particles but not used in our macroscopic world.
As a result of this, we can see that the reason for this is because there are certain frequencies at which the photons can be absorbed during the electron change as energy becomes more random.
