Hello, we were provided two unknown samples and asked to determine if our samples were alcohols or not, using the 2,4-di-nitrophenyl hydrazine test. Then we tested our positive sample with Fehlings test to determine that we had a Ketone and other sample using Lucas Reagent to determine that we had a secondary alcohol. We were given these graphs for our unknown samples to determine the connectivity/molecular struture. Please kindly assist or let me know what other information would help with this lab. Thanks a million

One hundred random mud samples were taken from a lake bottom in order to determine whether two species of oligochaete worms occur together. In each sample, it was recorded whether there were zero, one or two species present. The scientist is interested in comparing the proportions of plots in which there are zero, one or two species (we are comparing each of the three proportions to the other two). Please identify the most appropriate statistical technique to use to answer...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
