- 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...
You just find the greatest common divisor of the number of atoms in the molecule. So, the greatest common divisor of six and six is obviously six, so you divide both of these by six and you get the empirical formula. It's not easy, or you pretty much can't go back from the empirical formula to the molecular formula.
