Title: Molecular Models lab questions
Post by: CombatWombat123 on March 08, 2019, 02:33:30 PM

Hi everyone, I'm having some trouble completing my lab and would love any help you can offer on these questions.

Thanks!

1. Both water and carbon dioxide are tri-atomic molecules. Both contain polar bonds. Explain why one molecule is polar and the other molecule is nonpolar

2. For the noble gas electron configuration, 2 electrons completely fill hydrogen's outer shell while the outer shells of the other elements can hold 8. Why?

Molecular shape name of

CH3OH (C Central, O central)

H2CO (C Central)

Thanks again!
