I want 1.0 L of buffer solution of pH 5.0, that can tolerate the addition of 0.3 mol HCl with out the pH changing more than 0.1 pH unit. Describe how to prepare this solution

they begin to vibrate harder causing the material that was solid to turn into a liquid i.e gallium or ice

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.
