Multiple Choice

Attractions between the negative Oxygen atom of one water molecule and the positive Hydrogen atom of another water molecule are called

• Covalent bonds
• Ionic bonds
• Polar bonds
• Hydrogen bonds

Multiple Choice

The fact that ice floats on liquid water is due to the fact that ........

• as water freezes, it expands and its density decreases.
• as water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• as water freezes, air becomes trapped between the hydrogen bonds of water molecules.
• as water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Multiple Choice
