Why is the chemical formula of benzene C6H6? A benzene molecule consists of six hydrogen atoms and six carbon atoms. The valence of hydrogen is +1, and the common valence of carbon is +2 and +4. How do they make the valence algebra 0?

What is the definition of organic matter? What is the greatest difference between organic and inorganic substances? How to determine if a substance is organic?

There is no clear definition. But you only need to look at the CH class. Yes. In fact, HCO3- can also be written as organic formula, SO32-root can also be. According to the experience, organic matter refers to the compounds containing carbon elements. Carbon oxide, carbonate (hydrogen) salt and metal carbide.(such as carbon dioxide, sodium carbonate, etc.)
