Answer 2

I'm sorry, but I'm not sure I understand the notation you've provided. "N-3," "5ë," and "????Химия" don't seem to form a clear question or statement related to chemistry or any other topic. If you have a specific question or topic you'd like to discuss in the field of chemistry or need information, please provide more context or clarify your request, and I'd be happy to help.
