Hello, I'm Amp71. An edit that you recently made to Resonance (chemistry) seemed to be a test and has been removed. If you want more 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! Amp71 (talk) 04:53, 12 February 2019 (UTC)
