Multiple Choice
Water is cohesive and sticks to other water molecules. How does water stick to other water molecules?
A positively charged hydrogen of one water molecule bonds to the negatively charged oxygen of another water molecule
A negatively charged hydrogen of one water molecule bonds to the positively charged oxygen of another water molecule.
The oxygen of one water molecule bonds to the oxygen of another water molecule
A hydrogen of one water molecule bonds to a hydrogen of another water molecule

Multiple Choice
Why is water polar?
There are no charges on either end of a water molecule
The electrons are evenly distributed
The electrons are unevenly distributed
Water is a covalent bond sharing the electrons between hydrogen and oxygen equally.
