Nitrogen dioxide reacts with water to form nitric acid and nitrogen monoxide according to the equation:3NO2(g)+H2O(l)→2HNO3(l)+NO(g)
Suppose that 4.5 mol NO2NO2 and 0.40 mol H2OH2O combine and react completely. Which reactant is in excess?
Give the IUPAC name for each of the following
A 0.16 mol dm−3 solution (3.50 cm3) of s-butyllithium in toluene wasadded to a solution of styrene (8.40 g) in toluene (200 cm3). Aftercomplete conversion of the styrene, isoprene (28.00 g) was added.When the isoprene had completely polymerized, the reaction wascompleted by additionof a 0.10 mol cm-3 solution (2.80 cm3) of dichloromethane in toluene.(a) Write down the reactions occurring in each stage of this reactionsequence and show the structure of the final polymer. (b) Evaluate therelevant degrees of polymerization and the corresponding molar massesfor the final polymer.
