Question

Which best describes how to classify water?

Answer 1

Answer:

b)It is a compound because it is made of a single kind of molecule.

Explanation:

Answer 2

Answer:

D

Explanation:

Water is a compound and scientifically known as H$_{2}$0 (2 hydrogen atoms and 1 oxygen). Therefore, the answer is...

• Not A because water is not an element of one pure substance; rather, it is a compound and can be broken down into two pure substances.
• Not B because the statement contradicts itself: a compound is made of different atoms and, thus, different molecules.
• Not C because a mixture contains different substances that are physically -- not chemically -- combined. And as we know, water is a compound, which means that its atoms are chemically bonded to one another. Or else it would just be 2 free hydrogen atoms and 1 oxygen.
• D (yay!) because it is not the *most* accurate, but simply the best description of those provided. Water can be described as a homogenous (uniform in appearance) mixture because, minus the "mixture" part, that's what it is, essentially: a substance that looks pure but is really made of up different molecules.

Ngl this was tricky, but I hope this helps :)
