Chapter 4.1, Problem 5SSC

Interpretation Introduction

Interpretation:

Number of atoms of Elements A and B formed in each particle needs to be determined, if six atoms of Element A are combined with 8 atoms of element B to product six compound particles.

Concept introduction:

An element is a pure substance that cannot be broken down by chemicals. It made completely of one type of atom. Atom is the smallest particle in the element that can neither be created nor be destroyed.

Answer to Problem 5SSC

The compound consists of 1 atom of A, 1 atom of B and 2 atoms of B are unused.

Explanation of Solution

If the six atoms of element A combine with 8 atoms of element B to produce six compounds particles, then each compound contains 1 atom of A and 1 atom of B and 2 atoms element B are not used.

The reaction goes like this:

$6A+8B=6AB+2B$

Conclusion

Hence, 1 A atom, 1 B atom is used to make one particle and 2 B atoms are unused in the whole process.
