Question

1. circle the letter of each sentence that is true about waters structure. a. water is made up of atoms bonded to form molecules. b. water contains half as many hydrogen atoms as oxygen atoms. c. water molecules tend to push away from each other. d. the chemical formula for water is h2o. 2. one side of the water molecule has a positive charge, while the other side has a negative charge. what do the charges indicate about the molecule? a. water is a polar molecule. c. water is an ionic compound. b. water is a nonpolar molecule. d. water is an ion. 3. bonds that form between water molecules are called

Explanation:

1. Water is made up of two hydrogen atoms bonded to one oxygen atom (H₂O), so a is false. Each water molecule has two hydrogen atoms for one oxygen atom, not half as many hydrogen as oxygen, so b is false. Water molecules are attracted to each other due to hydrogen - bonding, not pushing away, so c is false. The chemical formula for water is H₂O, so d is true.
2. Water is a polar molecule because one side has a positive charge and the other has a negative charge due to the unequal sharing of electrons between hydrogen and oxygen. So the answer is that the charges indicate it is a polar molecule.
3. The bonds that form between water molecules are called hydrogen bonds.

Answer:

1. d. The chemical formula for water is H₂O.
2. a. Water is a polar molecule.
3. Hydrogen bonds.
