Determine the identity of the daughter nuclide from the electron capture by 84be.

Chemistry

anyanavicka [17]3 years ago
7 0
Answer:
8  Li3

Explanation:

1) Electrons are called beta radiation (β)

2) Electrons are considered massless and with 1 negative charge, so in the nuclear reactions they are written as:
 0   e-1

Which means that they do not change the mass number of the isotope but reduces its atomic number in 1.

2) Then, the capture of one electron by berylium-8 means that it will reduce its atomic number in one unit and while its mass number will be the same.

3) The given isotope is:
 8
    Be  4


4) Then the resultant daughter will have the same mass number (8) and aomic number 3.

The element with atomic number 3 is Li, so it will be:

8  Li3


5) The total nuclear reaction is:

8               0         8
  Be + 1      e →     Li
4              -1         3

The chemical equation of the reaction between Hydrogen and Oxygen is given below
Firdavs [7]

Answer:

1. a. The reactants are H₂ and O₂; The product is H₂O

b. The equation is not balanced because the number of atoms of the elements reacting is not equal to the number of atoms produced. 2 atoms of oxygen reacted but only one atom of oxygen is produced.

c. 2 H₂ + O₂ ---> 2 H₂O

2. a. The monotonic molecule is the sodium molecule, Na, since itnis made up of only one atom in its molecule.

The diatomic molecule is oxygen molecule, O₂, since it is made up of two atoms in its molecule.

b. The chemical compound present is sodium oxide, Na₂O

c. 4 Na + O₂ ---> 2 Na₂O

Explanation:

In a chemical reaction, the reactants are the elements or compounds which are converted to a new substance whichnis known as the product. The products are the new substances formed from the reactants.

In the given equation of reaction below;

H₂ + O₂ ---> H₂O

a. The reactants are H₂ and O₂; The product is H₂O

b. The equation is not balanced because the number of atoms of the elements reacting is not equal to the number of atoms produced. 2 atoms of oxygen reacted but only one atom of oxygen is produced.

c. 2 H₂ + O₂ ---> 2 H₂O

2. Given the reaction equation below:

Na + O₂ ---> Na₂O

a. The monotonic molecule is the sodium molecule, Na, since it is made up of only one atom in its molecule.

The diatomic molecule is oxygen molecule, O₂, since it is made up of two atoms in its molecule.

b. The chemical compound present is sodium oxide, Na₂O since itconsists of two chemically combined elements, sodium and oxygen.

c. 4 Na + O₂ ---> 2 Na₂O
