Why would a peretual machine never work?

Because magnets wear out. Magnetic perpetual machines can never work because magnets eventually wear out. This isn't the reason they don't work. Magnets can lose their magnetism in several ways; Heat them to very high temperatures. Hit them repeatedly with a hammer.

It'd never work as the first law of physics is that the law of conservation of energy. It states that energy is often preserved. To keep a machine moving, the energy applied ought to stay with the machine with none losses. As a result of this reality alone, it's not possible to make perpetual motion machines.

Hope it helps!<3

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

a polar bond is formed when electrons are shared unevenly between atoms
