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.

Astudent is trying to create a table that compares hypotheses, theories, and laws. hypothesis theory law do scientific researchers formulate it? yes yes yes does it explain why things happen? yes yes no yes yes yes is it used to make predictions? no yes yes which of the following questions would most likely fill the blank in the table? is it an intelligent guess? is it newly formulated? is it based on observations? has it been proved?
