Many of the unique properties of water are attributed to the fact that water . A. is a universal solvent B. requires heat to condense C. contains ionic bonds D. exists in three states of matter on Earth's surface E. is a polar molecule

E. is a polar molecule

Explanation:

The polar nature of the water molecule , i.e. , the atoms can be split into the respective partial positive as well as partial negative charge is referred to as a polar molecule .

Due to the electronegativity difference between the hydrogen and oxygen atom , i.e. , oxygen is more electronegative than hydrogen atom , so the oxygen atom attains a partial negative charge and the hydrogen atom attains a partial positive charge .

Hence , due to this polar nature of water molecule , it shows various unique properties .

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
