Consider the aldol condensation between dibenzyl ketone and benzil in strong base. A reaction was performed in which 0.70 g of dibenzyl ketone was reacted with 0.70 g of benzil to make 0.73 g of 2,3,4,5‑tetraphenylpentadienone. Calculate the theoretical yield and percent yield for this reaction.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

the answer is true. hope it .

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.

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
