Where did the original atmospheric oxygen come from?
Mostly from plants.
"An increase in atmospheric oxygen" An increase in atmospheric oxygen
A molecule of ozone is triatomic. A molecule of atmospheric oxygen is diatomic.
Oxygen which comes from the synthesis of glucose. Oxygen is the by product of 6CO2 + 6H2O to make C6H12O6 releasing three Oxygen (O2) molecules for every molecule of glucose produced.
oxygen fixes atmospheric nitrogen
The absence of free atmospheric oxygen means that the atmosphere does not contain any elemental oxygen (O2). Any oxygen is locked away in compounds such as carbon dioxide.
You need to distinguish between oxygen gas and atmospheric oxygen. Oxygen gas is 16 grams per mole, while atmospheric oxygen (O2) has twice the amount of oxygen and, therefore, weighs 32 grams.
while the atmospheric pressure at mountain is 260mmhg
The surface reacts with atmospheric oxygen, or atmospheric pollutants
Atmospheric pollution is found in the troposphere. It is also containing the oxygen.
No. The Ozone layer is a product of the atmospheric chemistry of Earth. It forms when high-energy photons interact with atmospheric oxygen in the reaction 3O2->2O3. Since the moon has no atmospheric oxygen (and in fact has no atmosphere), there is no ozone layer there.
Nitrogen and Oxygen
The atmospheric molecule is the diatomic Oxygen molecule, O2.
Water scorpions have air tubes that stick out of the water surface to take in atmospheric oxygen. They come up to the surface several like Dolphins and Whales.
I don't understand how CPR works we breathe in oxygen and we exhale CO2 so how come during CPR when we breathe into the person we are exhaling CO2 into there body insted of oxygen?
Atmospheric air has about 20.5% oxygen and our lungs only extract about 4.5% oxygen, so the air we exhale has about 16% oxygen, 4.5% CO2. The air we breathe into the victim then has 16% oxygen for their lungs to extract oxygen from.
Yes,plants do respire.During the day they utilize the atmospheric gases for photosynthesis.The oxygen produced as a by-product is utilized for respiration and the excess of the oxygen is given out.However,at night they use the atmospheric oxygen to respire giving out carbon dioxide.
Aside from bubbles, there is no "air" in water, however oxygen and other atmospheric gases, such as oxygen or nitrogen, may readily absorb into water. Water is after all made up of two atmospheric gases, hydrogen and oxygen.
Oxygen -Sabrina (:
Most of the atmospheric oxygen occurs as a result of photosynthesis From which of the following molecules is the oxygen derived?
The oxygen in photosynthesis is derived from water.
Hyperbaric oxygen therapy is the medical use of oxygen at a level higher than atmospheric pressure.
It is the name for the harmful effects of breathing oxygen at greater than atmospheric pressure.
There is no atmospheric oxygen, as the Martian atmosphere is mostly carbon dioxide (95.3%).
No, 20% oxygen is the normal atmospheric level.
Oxygen is the principal component of atmospheric air (approx. 80 %).
Photosynthesis is the main source of atmospheric oxygen.
There is an increased amount of oxygen after completion of the photosynthetic process.
Twenty percent (20%) of the moon's atmospheric gases is made up of oxygen.
Oxygen and nitrogen react only at high temperatures.
Aqueous glucose and atmospheric Oxygen (O2).
Volcanoes (Novanet Answer)
Plants and anaerobic bacteria.
Thy come to the surface every ten min. To breathe atmospheric air. They do have gills, but they only act as a secondary oxygen source. They rely on their mouths much more.
The origin of oxygen (and other large elements) is from supernovae. On the smaller scale, the vast majority of our oxygen comes from ocean plants, from tiny algae to giant kelp. The atmospheric oxygen comes from the decomposition of water and carbon dioxide by organisms that use photosynthesis to make useful molecules in combination with the energy from sun light.
The main source of oxygen in the atmosphere is plants. This is because plants produce oxygen as a waste product of photosynthesis.
"Oxygen" is just an element. It has one atom. Atmospheric Oxygen (O2) has 2. Ozone (O3) has 3.
Sources of Atmospheric Oxygen VOLCANOES are an often over looked source of atmospheric oxygen. During an eruption, oxygen is often released during chemical reactions caused by the heat of Magma/Lava. Also, algae in the oceans produce the most oxygen in the world, but are usually overlooked in favor of the more glamorous "rain forests". Though the rain forests produce more oxygen per capita, the sheer size and surface area of the world's oceans ensure that… Read More
Ozone and oxygen are a bit similar. Ozone is a 3 atom and oxygen is 2 atom.
It is due to oxydisation.It react with the atmospheric oxygen
It contains mainly oxygen and hydrogen atoms
Temperature and atmospheric pressure
It never was - Nitrogen is the "major gas".
At the top of Mount Everest, the percentage of oxygen in the air is the same as that at sea level (about 21% oxygen). However, atmospheric pressure decreases as altitude increases, and the atmospheric pressure at the summit of Everest is 33% that of sea level. Therefore, there is 66% less oxygen than there is at sea level.
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
Not atmospheric oxygen. Titan's atmosphere is mostly nitrogen. Most other remaining portion is methane and hydrogen.
Oxygen is recycled through the interrelated processes of photosynthesis and cellular respiration.
Oxygen - O2 Which accounts for about 10% of our atmospheric oxygen. The 90% comes from algae.
