At elevated temperatures, methylisonitrile (CH 3NC) isomerizes to acetonitrile (CH 3CN): CH 3NC (g) → CH 3CN (g) At the start of the experiment, there are 0.200 mol of reactant (CH 3NC) and 0 mol of product (CH 3CN) in the reaction vessel. After 25 min of reaction, 0.108 mol of reactant (CH 3NC) remain. The average rate of decomposition of methyl isonitrile, CH 3NC, in this 25 min period is mol/min.

Two people each hold the end of a rope and create waves by moving their arms up and down. this wave is best classified as a transverse wave because a) both the rope particles and the wave are moving in the same direction. b) the wave is moving up and down as the particles of the rope move horizontally. c) the wave is moving horizontally as the particles of the rope move up and down. eliminate d) the wave is moving in a parallel direction with the motion of the person's arms.

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.
