Question

1. draw and label the water molecule below with: a. element symbol (h or o) b. identify the charged regions (+ and -) c. describe the water molecule in the space below referencing its polarity, and bond types. 7. draw and label how water molecules arrange themselves that allow for their unique properties to be displayed. a. label the elements (h and o) b. label the hydrogen bonds using a dashed line (---) c. identify the charged regions (+ and -)

Explanation:

Step1: Draw a water molecule

Draw an oxygen atom (O) in the center and two hydrogen atoms (H) attached to it at an angle (usually about 104.5 degrees). The chemical formula of water is $H_2O$.

Step2: Label element symbols

Label the central atom as "O" (for oxygen) and the two smaller atoms as "H" (for hydrogen).

Step3: Identify charged regions

Oxygen is more electronegative than hydrogen. So, the oxygen - end of the water molecule has a partial negative charge ($\delta-$) and the hydrogen - ends have partial positive charges ($\delta+$). Mark the oxygen atom with $\delta-$ and each hydrogen atom with $\delta+$.

Step4: Describe polarity and bond types

The water molecule is polar. The O - H bonds are covalent bonds. Oxygen's high electronegativity causes an unequal sharing of electrons in the O - H bonds, creating a dipole moment. This polarity allows water molecules to form hydrogen bonds with each other.

Step5: Draw water - molecule arrangement

Draw multiple water molecules around each other. The oxygen atom of one water molecule is attracted to the hydrogen atoms of neighboring water molecules.

Step6: Label elements in arrangement

Label the oxygen atoms as "O" and hydrogen atoms as "H" in the multiple - water - molecule drawing.

Step7: Label hydrogen bonds

Draw dashed lines to represent the hydrogen bonds between the oxygen of one water molecule and the hydrogen of another water molecule.

Step8: Identify charged regions in arrangement

Again, mark the oxygen atoms with $\delta-$ and hydrogen atoms with $\delta+$ to show the charged regions in the water - molecule arrangement.

Answer:

For question 6:

• The drawing has an oxygen atom in the center labeled "O" and two hydrogen atoms labeled "H" attached to it.
• Charged regions: Hydrogen atoms are labeled $\delta+$ and oxygen atom is labeled $\delta-$.
• Description: The water molecule is polar with covalent O - H bonds. Oxygen's high electronegativity leads to unequal electron - sharing, creating a dipole moment.

For question 7:

• The drawing shows multiple water molecules with oxygen atoms labeled "O" and hydrogen atoms labeled "H".
• Hydrogen bonds are shown as dashed lines between the oxygen of one water molecule and the hydrogen of another.
• Charged regions: Hydrogen atoms are labeled $\delta+$ and oxygen atoms are labeled $\delta-$.
