The word equation for wood combustion is that wood in the presence of oxygen and high heat combusts to produce carbon dioxide, water vapor, heat and ash residue. Wood combustion gives off heat because it is an exothermic reaction.Know More
Wood is made up of cellulose, an organic compound that is a polymer or macromolecule. Thermal decomposition of cellulose is the reason why wood ignites and combusts under the influence of heat. Another name for thermal decomposition is pyrolysis.
In the pyrolysis process, the application of high heat to wood causes the cellulose to begin its decomposition. The decomposing products react with the oxygen in air to produce more heat and a chain reaction that culminates in the release of the products carbon dioxide, water in gaseous form, ash residue and heat.Learn more about Chemistry
Gasoline burning is an example of a chemical change, because this process produces water vapor and carbon dioxide. For something to be categorized as a chemical change, it must form new chemical substances. It also entails making and breaking molecular bonds. Another example is iron rusting, which forms iron oxide.Full Answer >
A simple word equation that can be used to describe the process of photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate.Full Answer >
Aerobic respiration turns glucose and oxygen into water and carbon dioxide. The energy from this reaction is also used to recharge depleted ADP molecules into ATP, a molecule which is used to power many of the functions of the cell.Full Answer >
Iron is abbreviated as Fe on the periodic table of elements and is considered to be a ferrous metal in group 8. Ferrous metals are commonly known for being magnetic, and they rust in the presence of oxygen.Full Answer >
