Why is water considered a polar molecule? a. the molecule has no overall charge. b. the oxygen and hydrogen atoms share electrons equally. c. the atoms in the molecule have partial charges. d. the molecule can only attract positive charges. i personally deduct that it is c but i would love some other opinions! : )

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
