Answer to Problem 3.1P

9A2+6B6A3B

Or

3A2+2B2A3B

Given:

Element Arepresents red sphere and element Brepresents green spheres.

Explanation of Solution

In left box, reactant side, two red spheres are stick together and green spheres are independent. Therefore, box contain molecules of A2and B.

In right box, product side, compound formed by arrangement of A and B in the ratio of 3:1 is present. Therefore, box contain molecules of compound A3B.

A2+BA3B

By trial and error method, it can be found out A2has 3molecule, Bhas 2molecule while A3Bhas 2molecule.

Now balance equation can be written as:

9A2+6B6A3B

Or, it can be simplified as follows:

3A2+2B2A3B

Conclusion

Number of atom in reactant side = Number of atomic product side. Atoms are conserved during chemical reaction.
