While working in the laboratory, a technician accidentally knocks over a beaker and spills all 200.0 mL of 2.5 M HCl.
Which of the following would neutralize the spill and not have any base left over?

A) 200.0 mL of 2.5 M Ca(OH)2
B) 100.0 mL of 5.0 M KOH
C) 500.0 mL of 1.0 M NaOH
D) 125.0 mL of 2.0 MCa(OH)2
E) 250.0 mL of 2.0 MCa(OH)2

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.

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
