Delicate balance of \(CO_2\) and \(O_2\) is not disturbed by:
- Deforestation
- Respiration
- Burning of coal
- Burning of petroleum
The Correct Option is B
Solution and Explanation
The equilibrium between carbon dioxide (CO$_2$) and oxygen (O$_2$) in the atmosphere is primarily regulated by the process of photosynthesis in plants, which absorbs CO$_2$ and releases O$_2$. Conversely, respiration by both plants and animals releases CO$_2$ and consumes O$_2$.
Step 2: Identifying the correct process
While activities such as coal burning, deforestation, and petroleum combustion disrupt the delicate balance of CO$_2$ and O$_2$, respiration does not. Respiration is a natural process where the consumption of O$_2$ and the release of CO$_2$ are in balance, ensuring that atmospheric levels remain stable.
Therefore, respiration does not disturb the delicate balance.
Top Questions on Oxygen
- An organic compound contains 37.5% C, 12.5% H and the rest oxygen. What is the empirical formula of the compound?
- Which element is not present in Nessler's reagent?
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Polluted water may have a value of BOD of the order of 17 ppm.
Reason R: BOD is a measure of oxygen required to oxidise both the bio-degradable and non-biodegradable organic material in water.
In the light of the above statements, choose the most appropriate answer from the options given below.
C(s)+O2(g)→CO2(g)+400 kJ
C(s)+\(\frac{1}{2}\) O2(g)→CO(s)+100 kJ

Oxygen
Oxygen is an important element in the combustion process. It is a member of the chalcogen group on the periodic table which is one of the most abundant elements in the Earth’s crust.
Oxygen is very important for a living organism to survive, multiply, and for converting food into energy. It is the only living gas for human beings and they inhale it from their nose reaching to their lungs.
Only oxygen gas gives our cells the ability to convert food into energy which is very important for us to survive.
Oxygen is a chemical compound with the symbol O and atomic number 8.
Properties of Oxygen:
- Oxygen gas is odorless, colorless and insipid in a normal state. Liquid oxygen is slightly paramagnetic. It is reactive and forms oxides with every element except helium, neon, krypton, and argon. It is moderately soluble in water.
- It is one of the common allotropes of oxygen.
- Trioxygen is the most reactive allotrope of oxygen that would cause damage to lung tissue. This allotrope is termed as ozone.
