A group of giraffes feeds on leaves and grasses during the daytime. Right now, it is dark out and the giraffes are not eating. Is carbon dioxide moving into the living things, moving out of the living things, or both?

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

if you're asking what comes out, it's steam.
