Oxygen is not a special element 'needed' in so many reactions, though it is:
There are many chemical reactions that relase enegy but do not involve Oxygen at all. The decomposition of Nitrogen Triodide is an example. 2NI3 -> N2 + 3I2
Enzymes. These are biological catalysts that lower the activation energy needed for a chemical reaction to occur, allowing reactions to proceed at a faster rate under conditions suitable for life. Without enzymes, many of the chemical reactions necessary for life would not occur at a sufficient rate to support cellular function.
Yes , oxygen is a reactant but with different properties , if oxygen misses you cannot burn fire .
Anaerobic reactions are chemical reactions that occur in the absence of oxygen. This type of metabolism is common in many microorganisms and produces energy through processes such as fermentation or anaerobic respiration. Anaerobic reactions have a lower energy yield compared to aerobic reactions.
Oxygen is a reactive gas found in Earth's atmosphere. It plays a crucial role in supporting life through the process of respiration and is necessary for many chemical reactions to occur.
because many of your cells need oxygen to start chemical reaction processes such as mitosis and meiosis.
Compounds ending in oxide typically consist of an element bonded to oxygen. Oxides are formed by the combination of elements with oxygen, resulting in a chemical compound. These compounds are often involved in various chemical reactions and play important roles in many processes, such as oxidation-reduction reactions and inorganic chemistry.
Many of the chemical reactions in photosynthesis are redox reactions, involving both reduction and oxidation processes. In photosynthesis, carbon dioxide is reduced to sugars, while water is oxidized to produce oxygen.
There are many different chemical reactions which affect the color of chemicals that undergo those reactions.
Cooking involve many chemical reactions.
Oxygen is considered to be a good insulator. This is a non-metallic element that can be used for insulation purposes.
Water is known to be a universal solvent which work as medium for many chemical reactions. Water is so necessary for human or other living beings as it provide medium for many chemical reactions to take place which are essential for living and also it constitute the major part in blood, and excreation removal.
