Is leaves producing oxygen physical or chemical?
The process of leaves producing oxygen is a physical and chemical process. It involves photosynthesis which is a chemical reaction that converts sunlight, water, and carbon dioxide into glucose and oxygen. This process occurs in the chloroplasts of plant cells.
Reaction with oxygen is a physical or a chemical change?
Oxidation is a chemical process.
What process adds oxygen to earths atmosphere?
Photosynthesis
Chemical substances that are very influential in the process of chemical weathering are what?
carbon dioxide and oxygen
What process adds oxygen to the air?
Photosynthesis in plants adds oxygen to the air. That's because the process uses H2O (water). Photolysis (splitting with light) uses sunlight, or whatever source of light is being used by the plant, to split the water into H+ (positively charged hydrogen ions) and O2, oxygen atoms. The plant only needs the hydrogen ions, so the oxygen is released through the stomata of the plant's leaves. It then enters the atmosphere.
What is the chemical process that uses oxygen in the body?
Respiratory system
Is the compression of oxygen gases a chemical process?
No, compressing oxygen gas is a physical process, not a chemical one. The oxygen molecules themselves do not undergo any chemical changes during compression; they are simply being packed more closely together.
What is the process that removes oxygen from the air and adds carbon dioxide to the air?
Combustion. The burning of any material.
Is decomposition of water into hydrogen and oxygen a chemical process?
Yes, the decomposition of water into hydrogen and oxygen is a chemical process. It involves breaking the bonds between the hydrogen and oxygen atoms in water molecules to form new compounds (hydrogen gas and oxygen gas).
What process adds and removes gases from the atmosphere?
The process that adds gases to the atmosphere is volcanic activity, which releases gases such as carbon dioxide and sulfur dioxide. The process that removes gases from the atmosphere is photosynthesis, where plants absorb carbon dioxide and release oxygen.
What chemical weathering process is caused by oxygen and water acting on iron?
The chemical weathering process caused by oxygen and water acting on iron is called oxidation. This process results in the formation of iron oxide, commonly known as rust.
Is it a chemical or physical change when oxygen is incorporated into hemoglobin to bring it to the cells?
This is a chemical change. When oxygen binds to hemoglobin, it forms a new compound with a different chemical composition. This process involves breaking and forming chemical bonds.
