Hello, I'm Ingenuity. An edit that you recently made to Stoichiometry seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! >>> Ingenuity . talk ; 12:25, 3 June 2022 (UTC)
