Why are scientists now more excited about sound levitation than they had been previously? SELECT AN ANSWER

Sound levitation was previously only a theory and has only now been done experimentally.

By using sound levitation at the right frequency, scientists can break objects like glass.

The cost of sound levitation has decreased dramatically over the past decade.

Research has shown scientists can control the movement of liquids with sound without touching the liquid​

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
