1) Covalent bonds involve sharing of electrons. Tor F 2) lonic bonds involve transfer of electrons. Tor F
3) Metallic bonds contain a sea of mobile electrons. T or F
4) When electrons are gained, or lost ions are formed. T or F
5) VSEPR theory is not usefulin predicting shapes of molecules. T or F
6) Hybrid orbitals are formed from mixing of orbitals. T or F

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

particle   p is an electron and particle q is a neutron

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
