Calculate the concentration of a solution that was made by dissolving 56.00 g of KCl in 3.0 L of water and Determine the molarity of a solution that is prepared by diluting 170 mL of 0.600 M BaCl2 to produce 250 mL.

Adozen is 1221/12 = 1.751.75 x 12 = 21therefore, 1.75 is the answer.

Answer:

a. energy is absorbed in the reaction.

explanation:

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.

The atomic nucleus made up from protons (yellow) and neutrons (blue) and held together by nuclear forces. nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. they bind protons and neutrons (“nucleons”) into atomic
