So our teacher issued us a challenge to complete over spring break...the challenge is to make 2 dicatomus keys on how to many compounds such as co2. One for the metals spot and one for the nonmetals spot. The thing is he said we can only have 4 questions for each one...so if you guys could help me out it would be greatly appreciated.
