My lab partner and I did 3 trials and I created a data table from the information we got. I understand the principles of Charles' Law, but I am not sure how to use the data in relation to mathmatical caluculations we were instructed to do. Also, I am not quite sure what to write for the conclusion. Thankyou for all of your hard work in trying to help us gain more knowledge in the laboratory - I guess I just got really stuck this time!:) | | | Post Reply | Display replies to this message

Also,on the lab, when a product is found to be H2O (water), what is its symbol? Is it (aq) for aqueous? I had the same trouble with MgO. Is MgO (s) for solid? Also, is it necessary to memorize the entire activity series? | | | Post Reply | Display replies to this message

We were unable to explain how oxygen would hybridize when its valence is 2s2 2p4? Also, how would hybridization effect shape, that's related to lone pairs, correct?
Thanks, The Varners | | | Post Reply | Display replies to this message
