Question

When 6.3g of sodium bicarbonate is added to a solution of acetic acid weighing 15g,it is observed that 3.3g CO 2 is relesed to the atmosphere. The residue is found to weigh 18.0g .show that the data is in agreement with the law of conservation of mass.

Answer 1

Answer:

sodium bicarbonate + acetic acid solution=carbon dioxide+ residue

         (6.3g)                +            (15g)             =   (3.3g)           +   (18g)

21.3=21.3
