An experiment test of the Law of conservation of Mass is illustrated in the diagram. In practice, the flask is weighed before and after reaction between solutions X and Y. Which of the following pairs of solutions will be unsuitable for the experiments

X = hydrochloric acid; Y = silver nitrate

X = barium chloride; Y = dilute sulphuric acid

X = hydrochloric acid; Y = sodium hydroxide

X = hydrochloric acid; Y = lead nitrate

X = hydrochloric acid; Y = sodium carbonate
