-1. In simple inorganic compounds other than peroxides and superoxides, oxygen almost always has an oxidation number of -2, but since calcium cations always have an oxidation number of +2, in this compound, the two oxygen atoms must have only -1 charge each. This compound is calcium peroxide, one of the exceptions noted above.
Mo is at an oxidation state of 5+ in CaMoO4 the oxidation state of Mo in CaMoO4 is 6+
It's 6, because: each oxygen is -2 (-2 x 4 = -8), but there is a -2 charge on the compound so the sum of the oxidation numbers of Mo and O has to be -2. So, +6 plus -8 equals -2.
In MoO4 Mo would have an ON of +8 and oxygen -2. You probably mean MoO3 where Mo has an ON of +6 or conceivably the MoO42- ion where Mo also has an ON of +6
MoS2. -2 for each S, +4 for Mo
MoS2. -2 for each S, +4 for Mo
+1 for Na -2 for each O +5 for Mo
If you mean MoO4 the oxidation number of Mo is 8 and the compound would be called Mo(VIII) oxide. This compound does not exist, it is theoretical- teachers and examiners often use such nonexistent compounds as teaching aids- why I don't know- i think it is misleading as there are plenty of real compounds about.

It is different compound to compound. Sulfur generally shows +6 and +4.
oxidation number of I is -1. oxidation number of F is +1.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
Zn has oxidation number +2; S has oxidation number -2
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
The oxidation number for H is +1, and the oxidation number for O is -1.
