Which of these is NOT an example of a pure substance? A a tablet of the element known as calcium
11111nata11111 [884]

Answer:

a glass of muddy water

Explanation:

Pure substances contain only one element or compound.

Calcium is one element so it is a pure substance. Ice and water have the same molecular structure, so it is a pure substance. Aluminum oxide is a chemically pure compound.

The only example that is not a pure substance is muddy water due to the multiple components of mud mixing with the components of water.

Hope that helps.
