Water accounts for 50% of the weight of a young adult female and 60% of a young adult male. What kind of bond is found at "A"?
A) Hydrogen bond
B) Water molecule
C) Oxygen atom
D) Hydrogen atom
E) Polar covalent bond
Hydrogen Bond
A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
Polar Covalent Bond
A polar covalent bond is a type of chemical bond where electrons are unequally shared between atoms, leading to a distribution of electrical charge.
Water Molecule
A molecule consisting of two hydrogen atoms and one oxygen atom, chemically represented as H2O.

Final Answer :
E
Explanation :
The bond found at "A" in a water molecule is a polar covalent bond. This type of bond occurs when electrons are shared unequally between atoms, as is the case between the oxygen and hydrogen atoms in water. The oxygen atom attracts the shared electrons more strongly than the hydrogen atoms, creating a molecule with a partial negative charge near the oxygen and partial positive charges near the hydrogens.
