Q. 2.9 P - Chemistry: Molecular Nature Of Matter And Change

Question

Each scene below represents a mixture. Describe each one in terms of the number of elements and/or compounds present.

                

Step-by-Step Solution

Answer

1. A mixture of three elements and four compounds (two different types of compounds)
2. A mixture of four elements (two are uni-atomic and two are diatomic) and two compounds
3. A mixture of three diatomic and two triatomic elements

Step 1: Diagram a

Diagram a represents a mixture of three elements and four compounds. Element is the one which has only one type of atom while there are two different compounds.

 

Step 2: Diagram b

Diagram b represents a mixture of four elements (two are uni-atomic and two are diatomic) and two compounds. Here compound is made of 2 different types of atoms.

Step 3: Diagram c

Diatomic and triatomic elements are pure elements that form molecules consisting of two or three atoms bonded together. So, here diagram c represents a mixture of three diatomic and two triatomic elements.
