Answer:
Oxygen. Oxygen is the most abundant element contained within living organisms, composing about 65% of the human body.
Explanation:
Ionic bonds have high emelting point amf boiling point while covale t bonds have low melting point and boiling point.
ionic bonds cannot conduct electricity in solid state but can conduct in the molten state or when dissolves in water. while covalent bonds cannot conduct electricity in any state.
ionic bonds are soluble in water but insoluble in organic solvents while most covalent bonds are soluble in organic solvents but insoluble in water

Answer: Your friend is incorrect.
Explanation: If we have an object or something that isn’t moving, (let’s say a notebook on a desk). If there is change, and the notebook moves, there is acceleration. Force = Mass times acceleration, f = m*a. There has to be a force, first of all. If you touched the notebook and moved it, some of your energy is transferred and now the notebook has kinetic energy. If our system is you and the notebook, the total energy doesn’t change. the energy is transferred, but doesn’t change. Your friend is not correct. Please give brainliest hope this helped!
