Answer:
Na2S
Explanation:
Na2S: Na (always +1). S (-2) in this formula
CaSO4: Ca (always +2). O (-2). => S (+6) in CaSO4
S (0)
SO2: O(-2) => S (+4)
Hope this answer will help you! Have a nice day!
Oxidation state is the atom of an organic compound that implies the amount of oxidation. It's the completely hypothetical charges how an atom would if all links to atoms of different elements were entirely ionic. Integers that could be negative, positive, or zero which are commonly used to indicate oxidation states, and further calculation can be defined as follows:
Calculation:
[tex]\bold{Na_{2}S: Na(always +1) \cdot S (-2) }\\\\\bold{CaSO_4: Ca (always +2)\cdot O (-2) \to S (+6)\ \ in\ \ CaSO_4}\\\\\bold{S (0)}\\\\\bold{SO_2: O(-2) \to S (+4)}\\\\[/tex]
Therefore, the final answer is "[tex]\bold{Na_2 S}[/tex]".
