Question

the circles and dots in the boxes below represent atoms of two different elements. atoms touching each other are considered bonded as a compound. which box contains a heterogeneous mixture? a box n b box m c box l d box o

Explanation:

Step1: Recall mixture definitions

A heterogeneous mixture has non - uniform composition. A homogeneous mixture has uniform composition. An element consists of only one type of atom, and a compound consists of two or more different types of atoms bonded together.

Step2: Analyze Box N

Box N contains only one type of atom (all the same color), so it is an element, not a mixture.

Step3: Analyze Box M

Box M has a non - uniform distribution of elements and compounds. There are separate atoms and compounds present in a non - uniform way, which is characteristic of a heterogeneous mixture.

Step4: Analyze Box L

Box L contains only compounds of the same type, so it is a pure substance (a compound), not a mixture.

Step5: Analyze Box O

Box O contains only compounds of the same type, so it is a pure substance (a compound), not a mixture.

Answer:

B. Box M
