The correct option is 2.
Explanation:
In a nuclear reaction balanced we have that:
1. The sum of the mass number (A) of the reactants (r) is equal to the sum of the mass number of the products (p)![\Sigma A_{r} = \Sigma A_{p}](/tpl/images/1378/5388/41364.png)
2. The sum of the atomic number (Z) of the reactants is also equal to the sum of the atomic number of the products
So, let's evaluate each option.
1)![^{23}_{11}Na \rightarrow ^{24}_{11}Mg + ^{1}_{1}H](/tpl/images/1378/5388/cf6d5.png)
The mass number of the reactant is:
The sum of the mass number of the products is:
This is not the correct option because it does not meet the first condition (
).
2)
The mass number of the reactant and the products is:
Now, the atomic number of the reactants and the products are:
This nuclear reaction is balanced since it does meet the two conditions for a balanced nuclear equation, (
and
).
3)
The mass number of the reactant and the products is:
Now, the atomic number of the reactants and the products are:
This reaction does not meet the second condition (
) so this is not a balanced nuclear equation.
4)![^{23}_{12}Mg \rightarrow ^{24}_{12}Mg + ^{1}_{0}n](/tpl/images/1378/5388/1cf9a.png)
The mass number of the reactant and the products is:
This reaction is not a balanced nuclear equation since it does not meet the first condition (
).
Therefore, the correct option is 2.
I hope it helps you!
