Deuterium is an isotope of hydrogen. It isn't clear what you mean by "ultra-dense deuterium". In theory, deuterium can release huge amounts of energy, via nuclear fusion.

Dense materials usually mean the atoms are closer to each other. Sound waves travel by causing vibration and transfer of energy. The close the atoms, the easier it is to transfer the energy. As the result, sound travels fastest in solid, then liquid, the least in gas matters.
Dense DOES mean the same a Dark. Its the color and the texture such as black, brown, or navy blue.
When a wave passes from a less dense medium to a denser one, most of the wave energy is answer is reflected FALSE
when something is heavy does that mean it is really dense
steam is less dense than mist because the particles in steam have more energy so they are less dense and rise. but mist is denser because it does not rise into the atmosphere and simply lurks around on the floor and has less energy
