What is the daughter nucleus (nuclide) produced when 213 Bi undergoes alpha decay? Replace the question marks with the
1 answer:
The daughter nucleus (nuclide) produced is
When an alpha decay occurs, the daughter nucleus has its atomic number less than that of the parent nucleus by two units and its mass number less than that of the parent nucleus by four units.
If we write the nuclear equation, we will have;

Answer :
Dipole moments occur when there is a separation of charge. Dipole moments occur due to atoms electronegativity, where one atom has the ability to attract electrons towards it giving it a negative charge and the one deficient in electrons acquire a positive charge called as the bond moment.
But if the bond moments are equal and opposite in direction , they cancel each other and thus there is no net dipole moment in the molecule.
For example: In carbon dioxide , both the -C=O bonds are polar but as the molecule is linear and the the magnetic moments are equal and oppposite, they cancel each other and the molecule is non polar.
Answer:
<h2>0.38 moles</h2>Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.38 moles</h3>Hope this helps you
