The number of moles of oxygen in the gas is 1.5 L.
The correct option is (A).
<h3>What are moles? </h3>
The mole is the International System of Units' foundation unit of material quantity.
Given,
The volume of gas is 33.6 L
Pressure is 1 atm.
Temperature is 0°C
Molar gas volume is 22.4 L
There is no temperature and pressure is 1 atm.
By formula of moles, volume is divided by molar mass
Thus, option A is correct. 1.5 L.

physical
It can be chemical but it's usually physical as the molecular structure doesn't change
By taking hydrogen ions, certain bases directly lower the H+ than OH- concentration. Other bases break down to create hydroxide ions, which indirectly lowers the H+ concentration.
<h3>
What is the difference between acid and base?</h3>
H+ ion concentration is raised by an acid. A base is a chemical that, in an aqueous solution, produces hydroxide (OH-) ions, gives electrons, and receives protons. A donor of protons is an acid. A proton can enter a base. When dissolved in water, an acidic chemical compound produces a solution that has more H+ ion activity than clean water. A base is an aqueous material that releases hydroxide (OH-) ions, receives protons, or contributes electrons. A donor of protons is an acid. A base is a proton acceptor.
