Answer 1

The water molecule that exists in the greatest abundance is H2O. A sample of pure aluminum is a pure chemical substance, an element, and a homogeneous mixture.

Step-by-step explanation:

The water molecule that exists in the greatest abundance is H2O, also known as the regular water molecule. It is the most common molecule of water and is made up of two hydrogen atoms and one oxygen atom.

A sample of pure aluminum that is free of impurities can be described as a pure chemical substance, an element, and a homogeneous mixture. Pure aluminum is composed of only one type of atom, making it an element. It is also a pure chemical substance because it is not mixed with any other substances. Finally, it is a homogeneous mixture because its composition is uniform throughout.
