WebJan 21, 2015 · Kuba Dolecki. Jan 21, 2015. Ice floats on water because it is less dense than water. When water freezes into its solid form, its molecules are able to form more stable hydrogen bonds locking them into positions. Because the molecules are not moving, they're not able to form as many hydrogen bonds with other water molecules. WebBasically, pennies are two layers: a copper outer layer that is very thin, and a thick zinc interior. If there are any scores or cuts in the penny exposing the zinc in the middle, it will react with HCl according to this reaction: Zn (s) + 2HCl (aq) --> ZnCl2 (aq) + H2 (g) So, as the zinc in the penny reacts with the hydrochloric acid, it ... http://www.terrificscience.org/lessonpdfs/01FloatingEgg.pdf does shaving armpit hair reduce sweat
