The first-order irreversible exothermic liquid-phase reaction A -Bis to be carried out in a jacketed CSTR. Species A and inert I are fed to the reactor in equimolar amounts. The molar feed rate of A is 100 mol/min.(a) What is the reactor temperature for a feed temperature of 450 K?(b) Plot the reactor temperature as a function of the feed temperature.(c) To what inlet temperature must the fluid be preheated for the reactor to operate at a high conversion?What arethe corresponding temperature and conversion of the fluid in the CSTR at this inlet temperature?(d) What is the inlet extinction temperature for this reaction system?

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

it's c (engineer's do their work with mechanical stuff not on any living being)
