Gaseous ammonia chemically reacts with oxygen (O2) gas to produce nitrogen monoxide gas and water vapor. Calculate the moles of ammonia needed to produce 0.055 mol of water. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.

Iwill give extra points to who gets this right

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.
