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

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
