Answer:
is the oxidizing agent
Explanation:
An oxidizing agent is an element in a reaction that accepts the electrons of another element. It is typically hydrogen, oxide, or any halogen. In this case, it is oxygen. The answer is 02.

This is an incomplete question, here is a complete question.
Nitroglycerine (C₃H₅N₃O₉) explodes with tremendous force due to the numerous gaseous products. The equation for the explosion of Nitroglycerine is:
A scientist conducts an experiment to characterize a bomb containing nitroglycerine. She uses a steel, ridge container for the test.
Volume of rigid steel container: 1.00 L
Molar mass of Nitroglycerine: 227 g/mol
Temperature: 300 K
Amount of Nitroglycerine tested: 227 g
Value for ideal gas constant, R: 0.0821 L.atm/mol.K
In a second experiment, the total pressure is observed to be 58 atm. what is the partial pressure of the water vapor produced?
Answer : The partial pressure of the water vapor is, 20.01 atm
Explanation :
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical reaction is:
From the balanced chemical reaction we conclude that,
As, 4 moles of react to give 12 moles of
So, 1 moles of react to give
moles of
and,
As, 4 moles of react to give 1 moles of
So, 1 moles of react to give
moles of
and,
As, 4 moles of react to give 6 moles of
So, 1 moles of react to give
moles of
and,
As, 4 moles of react to give 10 moles of
So, 1 moles of react to give
moles of
Now we have to calculate the mole fraction of water.
Now we have to calculate the partial pressure of the water vapor.
According to the Raoult's law,
where,
= partial pressure of water vapor gas = ?
= total pressure of gas = 58 atm
= mole fraction of water vapor gas = 0.345
Now put all the given values in the above formula, we get:
Therefore, the partial pressure of the water vapor is, 20.01 atm
Among formic acid (HCOOH ) and sulfuric acid (H₂SO₄), formic acid is the weak acid. Acidic strength of any acid is the tendency of that acid to loose proton. Among these two acids formic acid has a pKa value of 3.74 greater than that of sulfuric acid i.e. -10. Remember! Greater the pKa value of acid weaker is that acid and vice versa. Below I have drawn the Ionization of both acids to corresponding conjugate bases and protons. The structures below with charges are drawn in order to explain the reason for strength. As it is seen in charged structure of formic acid, there is one positive charge on carbon next to oxygen carrying proton. The electron density is shifted toward carbon as it is electron deficient and demands more electron hence, attracting electron density from oxygen and making the oxygen hydrogen bond more polar. While, in case of sulfuric acid it is depicted that Sulfur attached to oxygen containing proton has 2+ charge, means more electron deficient as compared to carbon of formic acid, hence, more electron demanding and strongly attracting electrons from oxygen and making the oxygen hydrogen bond very polar and highly ionizable.
