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:

a. A water molecule has two hydrogen (H) atoms and one oxygen (O) atom. The oxygen is in the center with hydrogen atoms bonded to it.
b. Oxygen is more electronegative than hydrogen. So, the oxygen - rich end of the water molecule has a partial negative charge (-), and the hydrogen - rich ends have partial positive charges (+).
c. Water is a polar molecule due to the unequal sharing of electrons between oxygen and hydrogen. The bonds between hydrogen and oxygen are covalent bonds. In terms of the unique properties - water molecules arrange themselves through hydrogen bonds. The hydrogen of one water molecule is attracted to the oxygen of another water molecule. The oxygen has a partial negative charge and hydrogen has a partial positive charge which allows for these hydrogen - bond interactions.

Answer:

6.
a. Draw a water molecule with an 'O' in the center and two 'H's bonded to it.
b. Mark the oxygen region with a '-' and each hydrogen region with a '+'.
c. Water is a polar molecule. The bonds between H and O are covalent. The oxygen is more electronegative, creating partial charges: oxygen has a partial negative charge and hydrogens have partial positive charges.
7.
a. Draw multiple water molecules. Label the 'O's and 'H's in each molecule.
b. Use dashed lines to show the hydrogen bonds between the oxygen of one water molecule and the hydrogen of another.
c. Mark the oxygen - rich regions with '-' and hydrogen - rich regions with '+'.
