Joan needs a 0.053-M solution of HCl, but only has access to 2.12-M HCl, a 10-mL graduated pipet, and a 25-mL volumetric flask. How much HCl should she measure to create her desired solution

Joan should measure 0.625 mL of 2,12 M HCl solution to create her desired solution.

Explanation:

Molarity of HCl Joan has access to =

Volume of 2.12 M of HCl Joan use =

Molarity of HCl Joan desired =

Volume of 0.053 M of HCl Joan can prepare =

Joan should measure 0.625 mL of 2,12 M HCl solution to create her desired solution.

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.
