In the equation given above, the oxidizing agent is FeO.
An oxidizing agent in a chemical reaction is defined as that substance, which has the capacity to oxidize other substances by gaining electrons from them. In a chemical reaction, an oxidizing agent is usually reduced by gaining electrons.
In the chemical equation given above, iron ll oxide oxidizes carbon monoxide to carbon dioxide.

In the reaction; FeO + CO → Fe + CO2, FeO is the oxidizing agent.

<h2>Further Explanation</h2><h3>Redox reactions </h3>
  • Redox reactions are types of reactions that involve both oxidation and reduction occurring simultaneously.  In these reactions one of the reactant undergoes oxidation while another undergoes reduction.
<h3>Oxidation </h3>
  • Oxidation involves the loss of electrons by an element. When an element or an ion undergoes oxidation, it looses electrons.
  • For example; in the above reaction carbon monoxide undergoes oxidation.
  • C²⁺ → C⁴⁺ + 2e
<h3>Reduction </h3>
  • Reduction refers to the gain of electrons by an element. Therefore, when an element or an ion undergoes reduction it gains electrons.
  • For example; in the above reaction iron (ii) oxide undergoes reduction.
  • Fe²⁺ + 2e → Fe
<h3>Oxidizing agent</h3>
  • An oxidizing agent in a chemical reaction is defined as that substance, which has the capacity to oxidize other substances by gaining electrons from them. In a chemical reaction, an oxidizing agent is usually reduced by gaining electrons.
  • In the chemical equation given above, iron ll oxide oxidizes carbon monoxide to carbon dioxide. 
<h3>Reducing agent </h3>
  • A reducing agent in a chemical reaction is defined as that substance, which has the capacity to reduce other substances by losing electrons from them.
  • In a chemical reaction, a reducing agent is usually oxidized by loosing electrons.
  • In the chemical equation given above, carbon monoxide reduces iron (ii) oxide to iron metal.

A 3.00-L flask is filled with gaseous ammonia, NH3. The gas pressure measured at 27.0 ∘C is 2.55 atm . Assuming ideal gas behavi
Whitepunk [10]

Answer : The mass of ammonia present in the flask in three significant figures are, 5.28 grams.

Solution :

Using ideal gas equation,

PV=nRT\\\\PV=\frac{w}{M}\times RT

where,

n = number of moles of gas

w = mass of ammonia gas  = ?

P = pressure of the ammonia gas = 2.55 atm

T = temperature of the ammonia gas = 27^oC=273+27=300K

M = molar mass of ammonia gas = 17 g/mole

R = gas constant = 0.0821 L.atm/mole.K

V = volume of ammonia gas = 3.00 L

Now put all the given values in the above equation, we get the mass of ammonia gas.

(2.55atm)\times (3.00L)=\frac{w}{17g/mole}\times (0.0821L.atm/mole.K)\times (300K)

w=5.28g

Therefore, the mass of ammonia present in the flask in three significant figures are, 5.28 grams.
