The decomposition of water into hydrogen gas H2 and oxygen gas O2 can be modeled by the balanced chemical equation
H2 + 02 H20
B)
H20 - H2+02
2H2 + O2 + 2H20
D)
2H20 – 2H2 + O2

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
