Which of these was the first source of oxygen in our atmosphere?
They were the oldest organisms called Stromatolites which did not need oxygen themselves but produced it by photosynthesis.
In photosynthesis the oxygen atoms from where are released as oxygen?
Oxygen released comes directly from the water used as a reactant. A plant enzyme splits water into protons, electrons and oxygen, with the electrons replenishing lost electrons in pigments, protons used to maintain the electrochemical gradient, and oxygen released as waste.
How much heat is released when methane and oxygen are burned?
890 kJ of energy are released when I mole of methane (16 g) is completely burned in oxygen.
How did oxygen get in your atmosphere?
Oxygen was released from Precambrian rocks. cynobacteria were the first organisms to produce oxygen 2.5-3 billion years ago
What happens when two oxygen molecules combine to form a molecule of oxygen?
Chemical bonds are formed and energy is released.
Why Isn't underwater volcanoes the right answer for most oxygen enters the ocean from?
Volcanoes do not release oxygen; they re;ease other gasses such as carbon dioxide and sulfur dioxide. The oxygen on earth is released by photosynthesizing organisms such as plants and algae.
What are the release dates for NASA 360 - 2008 Volcanoes Making Oxygen from Lunar Soil 1-8?
NASA 360 - 2008 Volcanoes Making Oxygen from Lunar Soil 1-8 was released on: USA: 20 March 2009
Can lakes near the volcanoes become acidic and why Is a fact or fiction?
Yes. One of the common gasses released by volcanoes is sulfur dioxide. This reacts with water and oxygen to form sulfuric acid.
Do volcanoes have oxygen?
No. A volcano erupts molten material from inside the earth. Actual fire is not involved:the material is hot to begin with and has been since the formation of the earth.
What types of gas do volcanoes emit?
oxygen
Which gas did volcanoes not produce in the Precambrian era?
Oxygen
What gas did volcanoes not produce in precambian era?
Oxygen
Which gas was not present on earth at its formation 4.6 billion years ago out of methane water vapour oxygen and nitrogen?
When the earth was formed, volcanoes were commonplace. These volcanoes released water vapor into the air, and produced gases filled with nitrogen, hydrogen, and carbon. The planet's atmosphere consisted of these gases and at the time, there was no free oxygen.
A frequently forgotten source of atmospheric oxygen is?
Volcanoes (Novanet Answer)
Which of these was the first source of oxygen in our atmosphere?
They were the oldest organisms called Stromatolites which did not need oxygen themselves but produced it by photosynthesis.
The magma released from volcanoes is?
lava
What volcanic gas is released the most by volcanoes?
Volcanoes release H2S, HCl, SO2, CO2, etc.
