Explanation:
The electrons in the outermost electron shell are responsible for forming chemical bonds. These electrons are also known as valence electrons
The evidence that a chemical reaction occurred is can be change in color , formation of a precipitate , Here in the case when 6 m HCl to the solution of sodium acetylsalicylate, the formation of precipitate that is of aspirin takes places that can be taken as a evidence that a reaction is occured. The reaction can be seen in the image attached.
Answer: (1.5 M) V1 = (3.40 M) (500mL)
(multiply 3.40M x 500mL) V1 = 1700 mL
1700 mL of the 1.5 M NaCl + 1200mL of water.
