Which represents a balanced nuclear equation?

The recent schools question and answer enquired students to claim what they consider is the most important challenge for a student to do in order to become success. One that response stood out from the rest was practice. Successful persons are usually not born successful; they become successful via hard work and dedication. If you wish to reach your goals, keep this in mind! followed below some question and answer examples that you could potentially utilize to further enhance your knowledge and gain insight that will assist you to sustain your school studies.

Question:

Which represents a balanced nuclear equation?

a. 23/11 Na —-> 24/12 Mg +1/1 H
b. 24/11 Na—-> 24/12 Mg +1/-1 e
c. 24/13 Al —->24/12 Mg+0/-1 e
d. 23/12 Mg—> 24/12 Mg +1/0 n

Answer:

Option b:

A nuclear equation is said to be balanced if the sum of the mass number A and sum of the atomic number Z is equal on both sides of the reaction arrow.

In nuclear reaction, atoms are represented as follows:

Here, A stands for mass number, Z stands for atomic number and X represents the atomic symbol.

a. The nuclear reaction is as follows:

Here, sum of mass number and atomic number on left side of the reaction arrow is 23 and 11 respectively.

On right hand side sum of mass number is 24+1=25 and that of atomic number is 12+1=13. Since, both mass number and atomic number are not same, it is not a balanced nuclear reaction.

b. The nuclear reaction is as follows:

Here, sum of mass number and atomic number on left side of the reaction arrow is 24 and 11 respectively.

On right hand side sum of mass number is 24+0=24 and that of atomic number is 12-1=11. Since, both mass number and atomic number are same, it is a balanced nuclear reaction.

c. The nuclear reaction is as follows:

Here, sum of mass number and atomic number on left side of the reaction arrow is 24 and 13 respectively.

On right hand side sum of mass number is 24+0=24 and that of atomic number is 12-1=11. Since, atomic number is not same, it is not a balanced nuclear reaction.

d. The nuclear reaction is as follows:

Here, sum of mass number and atomic number on left side of the reaction arrow is 23 and 12 respectively.

On right hand side sum of mass number is 24+1=25 and that of atomic number is 12+0=12. Since, atomic number is not same, it is not a balanced nuclear reaction.

They could simply hopefully guide the student resolve the question by using the questions and answer examples. You can potentially then have a discussion with your classmate and continue the school learning by studying the subject with one another.
