Question

1. When 5 g of sodium hydroxide is added to 20 mL hydrochloric acid solution (15 g), it is
found that an aqueous solution of sodium chloride is formed (20 g). Show that these
observation are in agreement with the law of conservation of mass.
​

Answer 1

Answer:

Answer:We Can See That These Observation Are Proof Of Conservation of Mass as The Total Mass of Reactants Is Equal To The Total Mass Of Products.

mass of sodium hydroxide + Mass of Hcl = Mass of Sodium Chloride

=)5g + 15 g = 20g

20g = 20g
