Where does the oxygen atoms in H2O come from?
The oxygen atoms in water (H₂O) come from the air we breathe. When we inhale, our lungs absorb oxygen from the air. This oxygen is then used in the process of cellular respiration to produce energy for our body's cells.
Can oxygen dissolve in water and how does this process occur?
Yes, oxygen can dissolve in water through a process called diffusion. This occurs when oxygen molecules in the air come into contact with the water's surface and move into the water due to differences in concentration. Once in the water, the oxygen molecules can be taken up by aquatic organisms for respiration.
What molecule did the oxygen we breathe originally come from?
The oxygen we breathe comes from the process of photosynthesis in plants, where they convert carbon dioxide and water into glucose and oxygen. The oxygen gas is released as a byproduct of this reaction.
What two substances must be present for iron to rust?
Iron must come into contact with oxygen and water for it to rust. This process is known as oxidation, where the iron reacts with oxygen in the presence of water to form iron oxide, the reddish-brown compound known as rust.
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.
What molecule does the oxygen gas come from?
Water
What sources do oxygen come from?
air water trees
Which elements come together to form water?
Hydrogen and Oxygen
What will rust?
Both water and oxygen are needed for rusting to occur.Iron and steel rust when they come into contact with water and oxygen. Both are present in the air.
Why doesn't Broccoli come in a can?
because it was grownin a field and if it is grown in a field the means it needs water and oxygen and in a can it has no oxygen
Where does the oxygen atoms in H2O come from?
The oxygen atoms in water (H₂O) come from the air we breathe. When we inhale, our lungs absorb oxygen from the air. This oxygen is then used in the process of cellular respiration to produce energy for our body's cells.
Why do fishes die when they come out of water even though oxygen is present in the atmosphere?
Fishes gills are designed only to extract oxygen when submerged. There is oxygen in water also, but our lungs cannot extract it.
From where does the oxygen liberated in photosynthesis come?
The oxygen liberated in photosynthesis comes from water molecules. During the light-dependent reactions of photosynthesis, water molecules are split into oxygen, protons, and electrons. The oxygen is released as a byproduct.
What do reptiles use to get oxygen from water?
Reptiles don't get oxygen from the water. All reptiles have to come up to the surface to breathe, but can hold their breath a long time.
Can oxygen dissolve in water and how does this process occur?
Yes, oxygen can dissolve in water through a process called diffusion.

What comes in and out in a plant?
sunlight, water and carbon dioxide go in, water vapor, sugars and oxygen come out
Where does the oxygen made during photosynthesis come from?
It comes from the splitting of water molecules.
