About this unit
Unlock the world of chemical reactions! Get ready to decode the language of chemistry, using symbols and equations to gain a deeper understanding of how substances interact and change at the atomic level. We'll also explore the underlying energy shifts that drive these reactions, laying a solid foundation for more advanced chemical concepts.

- A double bond is where there are four electrons shared between two atoms. You will learn more about these in future videos.
- The parenthesis in chemical formulas are from things called polyatomic ions. They’re basically groups of atoms with shared charges (mini molecules...
- It is derived from the molecular formula. Refer to this video : https://www.youtube.com/watch?v=ucU5PD6W3Ik
- Yes, entirely correct. 2H per 1O, or otherwise 1O per 2H
- The following is the answer to your question. It's a molecular formula that can be written as C₆H₅CO₂H or C₇H₆O₂. I Hope this Helps!
- Here is an example. Glucose has the molecular formula C6H12O6. Its empirical formula is CH2O. Thus C, H and O are in the ratio of 1:2:1 .
- there is a video on this topic which explains it in detail, i would suggest you to gradually get there. simplified, double bonds occur when atoms s...
