Question

Дописати рівняння ядерної реакції 3Li7 + 2He4 = 5B10 + ?

Answer 1

Если применить закон сохранения зарядовых чисел, то получим z=0 (внизу)
Если применить закон сохранения массовых чисел, то получим M=1 ( вверху)
То есть, это частица нейтрон  ₀ n¹

Answer 2

Nuclear Reaction Equation:

The nuclear reaction equation for the given reaction can be written as:

3Li7 + 2He4 = 5B10 + ?

This equation represents the reaction between lithium-7 and helium-4 to produce boron-10 and an unknown particle.

Balancing the Nuclear Reaction Equation:

To balance this nuclear reaction equation, we need to ensure that the total mass number and the total atomic number are conserved on both sides of the equation. Let's balance the equation step by step:

1. Balancing the Mass Number: - The mass numbers of the reactants and products are: - Lithium-7 (3Li7): Mass number = 7 - Helium-4 (2He4): Mass number = 4 - Boron-10 (5B10): Mass number = 10

- To balance the mass number, we can calculate the total mass number on both sides of the equation: - Reactants: 7 + 4 = 11 - Products: 10 + (mass of the unknown particle)

- To balance the mass number, the mass of the unknown particle should be 1.

2. Balancing the Atomic Number: - The atomic numbers of the reactants and products are: - Lithium-7 (3Li7): Atomic number = 3 - Helium-4 (2He4): Atomic number = 2 - Boron-10 (5B10): Atomic number = 5

- The atomic number is already balanced, as 3 + 2 = 5.

Conclusion:

The balanced nuclear reaction equation for the given reaction is:

3Li7 + 2He4 = 5B10 + 1n

Where: - 3Li7 represents lithium-7 - 2He4 represents helium-4 - 5B10 represents boron-10 - 1n represents a neutron.
