Question

In a reaction 5.3 g of carbonate reacted with 6g of ethanoic acid. The products were 2.2 g of co2 0.9 g water (h2o) and 8.2 g of sodium ethanote show that these are inagreement with the law of onservation of mass.

Answer 1

Answer:

sorry for not telling you answer

Answer 2

Sodium carbonate + acetic acid → Sodium acetate + carbon dioxide + water

Solution :

Sodium carbonate + acetic acid → Sodium acetate + carbon dioxide + water

5.3g 6g 8.2g 2.2g 0.9g

As per the law of conservation of mass, the total mass of reactants must be equal to the total mass of products

As per the above reaction, LHS = RHS i.e., 5.3g + 6g = 2.2g + 0.9 g + 8.2 g = 11.3 g
