Answer is: the oxidation number of oxygen must decrease.
Oxidizing agent is element (substance) that gain electrons in chemical reaction.
For example, balanced chemical reaction: C + O₂ → CO₂.
Oxygen change oxidation number from 0 to oxidation number -2 (reduction) and carbon change from 0 to +4 (oxidation)

Answer:
is the empirical formula of nerve agent.
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Molecular formula of nerve agent =
Number of carbon atoms = 11
Number of hydrogen atom = 26
Number of oxygen atom = 2
Number of phosphorus atom = 1
Number of sulfur atom = 1
Taking ratio of all atoms of different elements in the compound:
C : H : O : P : S = 11 : 26 : 2 : 1 : 1 = 11 : 26 : 2 : 1 : 1
The empirical formula of the nerve agent will be same as that of the molecular formula.
is its empirical formula.
