The complete chemical formula for the unknown compound is N2O3 where X = 2 which is the oxidation state of oxygen.
<h3>What is oxidation state?</h3>
Oxidation state is the number of electron which the compound is giving or taking from each other to form the bonds as the oxidation is hight oxidation is happening asn if the low then reduction is happening.
In the compound N2O3 the oxidation state of O is 2 and the oxidation stte of N is 3 written in the cross-cross manner in compound.
Therefore, N2O3 where X = 2 which is the oxidation state of oxygen is complete chemical formula for the unknown compound.

Answer:
54.075KJ
Explanation:
Since methane is the limiting reactant.
From the reaction equation,
16 g of methane absorbs 206 KJ of energy
4.20 g of methane will absorb 4.20 × 206/16 = 54.075KJ of energy was absorbed.
From the equation, the value of the enthalpy of reaction is positive, this means that energy is absorbed in the reaction of methane and water. Hence the answer.
