The iodination of acetone, ch3coch3, in aqueous solution is catalyzed by the hydrogen ion h+: i2+ch3coch3 h+⟶ hi+ch3coch2i the reaction can be followed visually by adding starch. the purple starch-iodine complex forms immediately, then disappears when the iodine has been consumed. the kinetics of the reaction may be determined by recording the time required for the color to disappear, which is the time required for the iodine, i2, to be consumed.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
