What Reaction Produces O2?

What Reaction Produces O2? Oxygen is generated by high-temperature decomposition of sodium chlorate: 2 NaClO3 → 2 NaCl + 3 O . Potassium permanganate also releases oxygen upon heating, but the yield is modest. What reaction is o2 produced? Oxygen atoms are created during the light process of photosynthesis, and two oxygen atoms then combine

What Sort Of Atmosphere Does Life Need To Survive?

What Sort Of Atmosphere Does Life Need To Survive? Carbon dioxide and oxygen are the gases in the atmosphere that are needed for life. Plants need carbon dioxide for photosynthesis. They use sunlight to change carbon dioxide and water into food. The process releases oxygen. Which layer of atmosphere is important for survival of life?

What Was The First Source Of Oxygen?

What Was The First Source Of Oxygen? The ability to generate oxygen via photosynthesis likely first appeared in the ancestors of cyanobacteria. These organisms evolved at least 2.45–2.32 billion years ago, and probably as early as 2.7 billion years ago or earlier. What was the first source of oxygen for Earth’s atmosphere? The answer is
