I think the help you are needed is about the conclusions right? So according to your statements and procedures i came up with the following conclusions:
1. When you read the formula, the geochemistry may not be correct but the liaisons would be correct. For example H2O could be linear or bent.
- They are similar where the number of liaisons/bonds are being used.
- The models may help when finding how the molecules would react with others, also the polarity.
