If 139 gm of zinc metal and 207 gm of copper II nitrate react. How many grams of
copper metal will be produced for this reaction?
Zn+Cu(NO3)2=zn (NO3)2 + cu

2-bromo-2-methylbutane undergoes an e1 elimination reaction in the presence of ethanol. in the next reaction only one of the possible products is represented. although the product shown is not the major product of the reaction, notice that there is more than one way it can be produced. complete the mechanism and draw the missing substances.
