Question

in a reaction , 5.3g of sodium carbonate reacted with 6g of acetic acid . the product were 2.2g of carbon dioxide,0.9g water and 8.2g of sodium acetate. show that these observation are in agreement with the law of conservation of mass .
​

Answer 1

Answer:

5.3g sodium carbonate + 6g acetic acid gives 2.2g carbon dioxide + 0.9g water + 8.2g sodium acetate

11.3g gives 11.3g

So, as mass of reactants = mass of products, this is in agreement with the law of conservation of mass.

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 !!! : )
