QUESTION :-

The oxygen that keeps us alive comes from ?

ANSWER :-

The oxygen that keeps us alive comes from plants as a product of photosynthesis.

Fundamental equation of photosynthesis proposed by C.B.Van neil :-

CO2 + 2H2O --------> CH2O(n) + H2O + 02

Balanced equation :-

6CO2 + 12H2O ------> C6H12O6 + 6H2O + 6O2

NOTE :-

The both reactions happens in the presence of light and chlorophyll

Oxygen is released into the atmosphere as a product which we breathe to be alive

Answer 2

Heya!


Here is ur answer....


The oxgyen that keeps us alive and useful for combustion comes from the PLANT as a product of Photosynthesis..

The equation of Photosynthesis is :
-------------------------------------------------



6CO2 + 12H2O -------> C6H12O6+6H2O+6O2



Here, if we observe the equation, 6 molecules of CO2 combines with 12 molecules of water to give One molecule of Glucose , 6 molecules of water , 6 molecules of oxygen.



So, oxygen comes from Plant as a product of photosynthesis.
