When Magnesium Reacts with Hydrochloric Acid, Aqueous Magnesium Chloride and Hydrogen

question 164

Short Answer

When magnesium reacts with hydrochloric acid, aqueous magnesium chloride and hydrogen gas are produced.Suppose 0.120 g Mg react with the HCl in a 75.000 g acidic solution contained in a calorimeter.The temperature increases by 6.03 $\degree$ C.Calculate the $\Delta$ H_rxn of Mg with HCl in kJ/mol.Assume the specific heats of the solution and of the empty calorimeter are 4.18 J/g . $\degree$ C) and 64.4 J/ $\degree$ C, respectively.

Definitions:

Chiral

Describes a molecule that is not superimposable on its mirror image, often leading to different reactions or interactions for each form.

Diastereomer

Molecules that are stereoisomers, not mirror images of each other and have more than one chiral center.

Diastereomers

Isomers of the same stereo configuration that differ in their physical properties and do not act as mirror images of each other.

Chiral

A term describing molecules or objects that cannot be superimposed on their mirror images, often leading to enantiomers in molecular systems.
