Unlike their counterparts, these reactors do not allow reactions to stay at steady state. For 10 points each:
[10m] Name these chemical reactors that add a reactant into a completed reaction in incremental large quantities rather than allowing the reactant to flow in at a constant rate. They are contrasted with continuous and plug flow reactors.
ANSWER: batch reactors [or batch process]
[10h] Due to large fluctuations in temperature following addition of batches of reactants, batch reactors are often regulated with these outer coatings. These structures contain refrigerants pumped through the exterior of the reactor.
ANSWER: cooling jackets [prompt on heat exchangers]
[10e] On the scale of a tabletop reaction, the massive impellers used to mix the reaction are usually replaced with these small magnetic tools. These tools spin rapidly when placed on a magnetized hot plate in order to mix a reaction.
ANSWER: stir bars [accept magnetic stirrer; accept magnetic mixer; accept flea]
