A reaction product is a substance formed in a chemical reaction; it is written to the right of the reaction arrow and accumulates as the reaction proceeds. Products result from the rearrangement of the atoms originally present in the reactants. For example, when methane burns, carbon dioxide and water are the products.

生成物(产物)是化学反应中生成的物质;它写在反应箭头右侧,并随反应进行而积累。产物由反应物中原有原子的重排得到。例如,甲烷燃烧时,二氧化碳和水是产物。
