i am looking for proof that oxygen comes from water and not from carbon dioxide. can you send me a link or a brief explanation on this subject? thanks.
Based on the treatment scheme, what type(s) of raw water is / are being treated? Groundwater
River water
Riverbank filtrate
Lake water
Infiltrated river water
please post answer
Certainly! The process of oxygen generation in plants is called photosynthesis. While it is true that plants do produce oxygen as a result of photosynthesis, it is important to note that this oxygen primarily comes from water, not carbon dioxide.
During photosynthesis, plants use sunlight, water, and carbon dioxide as the raw materials. In a complex series of reactions, the plants' chloroplasts (specific organelles responsible for photosynthesis) use the energy from sunlight to convert water and carbon dioxide into glucose (a sugar that serves as an energy source) and oxygen.
The specific reaction responsible for oxygen production during photosynthesis is as follows:
6 CO2 + 6 H2O + sunlight → C6H12O6 (glucose) + 6 O2
This equation shows that six molecules of carbon dioxide combine with six molecules of water, and with the help of sunlight, they produce one molecule of glucose and six molecules of oxygen.
To find more detailed information and scientific evidence supporting this process, you can refer to reputable scientific sources such as scholarly articles, textbooks, or educational websites. Some reliable websites include:
