PCl3(g)+Cl2(g) <--->PCl5(g)+energy
Question: Propose a mechanism for the forward reaction that is based on the molecular collision theory and describe each event (elementary process) in that mechanism.
A particular coal contains 2.92% sulfur by mass. When this coal is burned, the sulfur is converted into sulfur dioxide gas. The sulfur dioxide gas then reacts with calcium oxide to form solid calcium sulfite
In the preparation of the esters given in this experiment, the reaction product was extracted with 5% sodium bicarbonate solution in the isolation step. Why? What gas was evolved during this washing step? Write a balanced equation for the reaction..
An industrial freezer is maintained at -26 oC with a vapor compression refrigeration unit using R-134a (HFC-134a) as the working fluid. A throttle is used in the refrigeration cycle and the compressor is 80% efficient.
a radioisotope used to evaluate heart function in exercise stress tests, decays by capturing one of its own core electrons. it also emmits gamma rays. write an equation for its nuclear decay, then identify the daughter isotope
