Receiver Questions: 1) Going back to the idea of a plane before take off. Why was the sound of the engine louder when it goes from low to high power goes from low to high power?

There are two molecules with the formula C2H6O. Draw electron-dot structures for both. (Hint: The connection of atoms is different in the two structures.)
