Question

In a reaction, 5.3g of sodium carbonate reacted with 6g of ethanoic acid. The products were 2g of carbon dioxide, 0.9g water and 8.2g of sodium ethan oates. Show that these observations are in agreement with the law of conservation of mass.

Sodium carbonate+ethanoic acid-->sodium ethanoate+carbon dioxide+water.

Answer 1

These observations are not in agreement with law of conservation of mass as sum of mass of reactants not equals to sum of mass of products.

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 !!! : )
