Verify that this is a first order reaction by plotting 1n ([C2H40]/M versus time and determine the value of the rate constant.
Plaster of Paris, CsSO4 x XH2O, is a fractional hydrate; that is, one water molecule attaches to more than one formula unit. If a 2.002-g sample has a mass of 1.878 g after hearing, find the water of crystallizatioin (X), and write the formula for..
Write the structures of the products you would expect to get if you react N-cinnamaldehyde-m-nitroaniline with catalytic hydrogenation (that means adding H2 and Pt or Pd).
Draw and name the molecule which contains only carbon and hydrgen atoms only three of which are carbon
