Question

In a reaction, 5.3g of sodium carbonate reacted with 6g of ethanoic acid. the products were 2.2g of carbon dioxide. 0.9g water and 8.2g of sodium ethanoate. show that these observation are in agreement with the law of conservation of mass. sodium carbonate + ethanoic acid give raise to sodium ethanoate + carbon dioxide + water

Answer 1

5.3g+6g gives2.2g+8.2g+0.9g
11.3g = 11.3g
So it follow law of conservation mass because in law of conservation of mass
Total reactant=total product

Answer 2

Answer:

Heya !

Here is your answer ============================================================================

>> Mass of sodium carbonate = 5.3 g (given)

Mass of ethanoic acid = 6 g (given)

Mass of sodium ethanoate = 8.2 g (given)

Mass of Carbon dioxide = 2.2 g (given)

Mass of water = 0.9 g (given)

Now, total mass before the reaction = (5.3 + 6) g

= 11 . 3 g

And, total mass after the reaction = (8.2 + 2.2 + 0.9 ) g

= 11.3 g

total mass before the reaction = total mass after the reaction.

Hence, the given observations are in agreement with the law of conservation of mass.

Hope it helps !!! : )
