An empty Erlenmeyer flask weighs 257.1 g. When filled with water (d = 1.00 g/cm3), the flask and its contents weigh 552.9 g. (a) What is the volume of water in the flask? Enter your answer in scientific notation. (b) How much does the flask weigh when filled with the same volume of chloroform (d = 1.48 g/cm3)?

answer: mercury

explanation:

b.

the accuracy of the data.

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.
