When the temperature increases the atoms gain energy and the substance changes into a gas state.
The is the opposite when the temperature decreases and the liquid becomes solid ( in this case ice).
The answer is 4.0 moles of magnesium
because...
..
...4.0mol Makmol O2 =3.0mol O2
The answer is: a metal cation and the shared electrons that surround it.
Metallic bond is a type of chemical bond.
Metallic bond is formed between electrons and positively charged metal ions.
Metallic radius is defined as one-half of the distance between the two adjacent metal ions.
Metallic bond increace electrical and thermal conductivity.
Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.
I think that it's d) F- but I'm not sure.
