Suppose you want to determine which type of paper falls the fastest; an unfolded sheet of paper, a sheet of paper folded into fourths or a crumpled sheet of paper. you hypothesize that the crumpled paper falls the fastest. how would you use the scientific method to prove your hypothesis? i really need some with this one!

Plz me get these answer dubble cheak ur answer plz ppl i need it right

Calculate the expected ph values of the buffer systems from the experiments (a, b,c, d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i. e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.
