Explain what happens in a polar covalent bond.
When the electrons are not distributed equally and one element has more than the other
The hydrogen atom and the oxygen atom are held together by which kind of chemical bond in a water molecule?
They are held together by the polar covalent bond
Because of the type of chemical bond holding together the oxygen and hydrogen atoms in a water molecule, water molecules are described as being _______________ molecules.
polar molecules
The attraction between opposite charges of polar molecules is called a?
They are held together by the hydrogen bond
Explain why water is necessary for life on Earth.
Water is necessary because it is a good solvent and keeps us not dry
Is water an example of a biomolecule? Explain why or why not.
No, because water is not carbon-based, it cannot be a building block of life
Explain why water molecules stick together.
Water molecules are polar molecules and they stick together when placed to another water molecule
List and describe 5 unique properties of water that are caused by the hydrogen bonds formed between the polar water molecules.
Good solvent, floats while in solid form, is adhesive, is cohesive, high specific heat
