Question

objective: you will explore the unique properties of hydrogen bonds and water. scenario: an alien species from a faraway galaxy has landed on earth. they have never experienced water before. the aliens are very curious about the molecular shape and bonding involved in water molecules. they have also observed many phenomena they hypothesize are related to water. help the aliens learn more about this substance that makes life on earth possible. part 1: label the water molecules under extremely high magnification, the aliens have isolated two water molecules. color the water molecules below by shading the oxygen atoms red and leaving the hydrogen atoms white. label the partial chargers and specific bonds in the water molecules.

Explanation:

Step1: Identify oxygen and hydrogen atoms

Oxygen atoms are to be shaded red and hydrogen atoms left white as per the instruction.

Step2: Determine partial - charges

Oxygen is more electronegative than hydrogen. So, the oxygen atom in a water molecule has a partial negative charge ($\delta^-$) and each hydrogen atom has a partial positive charge ($\delta^+$).

Step3: Identify the bonds

The bonds between oxygen and hydrogen within a water molecule are covalent bonds. The dashed lines between water molecules represent hydrogen bonds.

Answer:

Shade the large circles (oxygen atoms) red and the small circles (hydrogen atoms) white. Label the oxygen atoms with $\delta^-$ and the hydrogen atoms with $\delta^+$. Label the solid lines connecting oxygen and hydrogen within a molecule as "covalent bonds" and the dashed lines between molecules as "hydrogen bonds".
