The material that is oxidized in the given reaction is Iron. Fe2O3 is iron oxide which can occur naturally as the mineral magnetite.
Carbon dioxide, of course. As the intermediate substrates of the CAC are being oxidized (NAD + to NADH ) carbon dioxide is being released to be expelled from the lungs.
The chemical equation you provided shows the reaction between formaldehyde (CH2O) and oxygen (O2) to form carbon dioxide (CO2) and water (H2O) as products. This is a combustion reaction where the organic compound is oxidized to produce carbon dioxide and water.
Carbon Dioxide
The reaction between KOH and CO2 to produce K2CO3 and H2O is a double displacement reaction, also known as a neutralization reaction. In this reaction, the ions in KOH and CO2 switch partners to form new compounds K2CO3 and H2O.
Non-metal oxides are compounds that are formed by the combination of a non-metal element with oxygen. They are typically acidic in nature and may react with water to form acids. Examples include carbon dioxide (CO2) and sulfur dioxide (SO2).
If the products of a reaction are carbon dioxide (CO2) and water (H2O), it suggests that the reactants likely include a carbon-containing compound (such as a hydrocarbon) and an oxidizing agent, typically oxygen (O2). This reaction is characteristic of combustion, where the carbon in the reactant is fully oxidized to CO2, and hydrogen is oxidized to form water. The complete combustion of hydrocarbons results in these specific products.
The product produced when C5H12O is oxidized depends on the degree of oxidation applied. If fully oxidized to formic acid (HCOOH), the reaction produces 5 moles of carbon dioxide (CO2) and 6 moles of water (H2O).
Photosynthesis is a redox reaction where water (H2O) is oxidized during the light reactions, leading to the release of oxygen as a byproduct. In the Calvin cycle, carbon dioxide (CO2) is reduced to form carbohydrates with the help of ATP and NADPH produced during the light reactions. Therefore, the correct options are c. oxidized...reduced.
CO2+H2O
Carbon dioxide, of course. As the intermediate substrates of the CAC are being oxidized (NAD + to NADH ) carbon dioxide is being released to be expelled from the lungs.

In this reaction, carbon (C) acts as a reducing agent. It reacts with lead oxide (PbO) to reduce it to elemental lead (Pb) while itself getting oxidized to carbon dioxide (CO2). This process is known as a redox reaction.

Carbon Dioxide
In the TCA cycle (Krebs cycle), the conversion of isocitrate to alpha-ketoglutarate is a redox reaction. During this process, isocitrate is oxidized, reducing NAD+ to NADH, while a molecule of CO2 is released. This reaction is catalyzed by the enzyme isocitrate dehydrogenase, highlighting its role in facilitating the transfer of electrons in metabolic pathways.
