Identify the elements present in the diagram. The green spheres represent one element, and the yellow spheres represent another element.
Observe the arrangement of the spheres. The green spheres are paired together, indicating they form diatomic molecules. The yellow spheres are single, indicating they are individual atoms.
Consider the decomposition reaction. A compound decomposes into its constituent elements. In this case, the compound must have contained both green and yellow spheres.
To draw the original compound, combine the green and yellow spheres in a way that represents a single molecule. Since the green spheres are diatomic, the original compound likely had a formula where one green diatomic molecule is bonded to one or more yellow atoms.
Draw a diagram with the green diatomic molecule (two green spheres) bonded to the yellow atoms. This represents the compound before decomposition.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Decomposition Reaction

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. This process often requires energy input, such as heat, light, or electricity. Understanding this concept is crucial for analyzing the diagram, as it illustrates the elements resulting from the breakdown of a compound.
