Sharks obtain all of their energy by eating other marine organisms, such as fish. suppose that a marine scientist measures the chemical energy found in a system consisting of a fish and a shark. after the shark consumes the fish, the marine scientist finds that the total energy in the system decreases. if true, would this result validate or invalidate the law of conservation of energy? why or why not?

sorry, but you do not have posted the diagram.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
