Hello, I'm Entranced98. I wanted to let you know that one or more of your recent contributions to Rwandan genocide have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help Desk. Thanks.

You may be blocked from editing without further warning the next time you vandalize Wikipedia, as you did at Martinique. David Biddulph (talk) 20:40, 7 January 2020 (UTC)[reply]

Incorrect bond angles

Methane is a perfect tetrahedraon, and all bond angles are 109.5 EXACTLY. The 108.7 shown in the figure is wrong and without reference.
