Answer:

C sound waves

Explanation:

Information processing starts with input from the sensory organs, which transform physical stimuli such as touch, heat, sound waves, or photons of light into electrochemical signals. The sensory information is repeatedly transformed by the algorithms of the brain in both bottom-up and top-down processing.

The best way seperate salt fron wateris with the use of

ExtremeBDS [4]

You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid. So, I would say maybe oil.

Polyatomic ions: $CH_3COO^-$ , $NO_3^-$ , $NH^+$ , $CN^-$ , $Li^+$ , and $OH^-$

Monatomic ions: $Ca^{2+$ , $O^{2-$ , and $Fe^{3+$

<h3>Monoatomic vs Polyatomic Ions</h3>

In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include $Ca^{2+$ , $O^{2-$ , and $Fe^{3+$

Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.

Examples of polyatomic ions are $CH_3COO^-$ , $NO_3^-$ , $NH^+$ , $CN^-$ , $Li^+$ , and $OH^-$

Thus, from the diagram:

Polyatomic ions: $CH_3COO^-$ , $NO_3^-$ , $NH^+$ , $CN^-$ , $Li^+$ , and $OH^-$

Monatomic ions: $Ca^{2+$ , $O^{2-$ , and $Fe^{3+$

Which statement best describes the behavior of most soilds?

lidiya [134]

B is correct. Molecules move faster when they are hotter because they have more energy. You can notice this change with your naked eye. Molecules in solids don't move. They have barely any energy. Hope this helps! ;)
