Question

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

Answer 1

Answer:

Mass of sodium carbonate = 5.3 g

Mass of ethanoic acid = 6 g

Mass of sodium ethanoate = 8.2 g

Mass of Carbon dioxide = 2.2 g

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.
