Which statement best describes the effect of radioactive decay on a nucleus?
KATRIN_1 [288]

When radioactive decay occurs, the original nucleus splits into daughter nuclei and the resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.

Unstable nuclei often undergo radioactive decay. In a radioactive decay, the unstable nucleus is broken up into other nuclei. Usually, the nuclei formed during radioactive decay are smaller in mass compared to the original nucleus.

Also, the resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.

10. a. What is the binding energy released when an alpha particle of mass 6.64 x 10-27 kg escapes from the nucleus of Uranium- 2
shutvik [7]

Answer:

The binding energy released is 1.992 X 10⁻¹⁸ J

Explanation:

Given;

mass of the alpha particle, m = 6.64 x 10⁻²⁷ kg

speed of the alpha particle, c = 3 x 10⁸ m/s

The binding energy released is given by;

E_b = mc^2

where;

m is mass of the particle

c is speed of the particle

E = 6.64 x 10⁻²⁷ (3 x 10⁸)²

E = 1.992 X 10⁻¹⁸ J

Therefore, the binding energy released is 1.992 X 10⁻¹⁸ J

Why do acids and bases have a good conduction of electricity?
omeli [17]
All acids only conduct electric current when they are dissolved in water, because when they are in an aqueous medium, they undergo ionization, i.e. release <span>ions.</span><span>

HCl --> H</span>⁺ + Cl⁻

The bases also conduct electric current in solution, because the Ionic dissociation sufferers (release the existing ions in the formula) and molecular ionization, suffer the reacting with water and releasing ions.

NaOH ---> Na⁺  + OH⁻

hope this helps!
