b. n=1, 1 = 1, m=-1

c. n=0, 1 = 0, m= 0

d. n=5, 1 = 1, m=3

Awhite powder is added to a solution. the images show observations made before the powder is added, just after the powder has been added, and a little while later. (the liquid in the small beaker is phenol red solution.) what evidence shows that a chemical change has taken place?
