Q:

Is water a Pure substance?

A) TRUE B) FALSE
Answer & Explanation Answer: A) TRUE

Explanation:

True, Water is a Pure substance and not a mixture.


 


We know that, A mixture is when two or more substances combine physically together. You can find that the mixture retains the properties of the original components.
