In a chemical reaction, 10.6g of sodium carbonate reacted with 12g of ethanoic acid. The products obtained were 4.4g of carbon dioxide, 16.4 of sodium ethanoate and 1.8g of water.
(a)Write a word equation, clearly showing the reactants and products as given above.
(b)Also show that this data is in aggrement with the law of conservations of mass.

Explanation

(a)The word equation for the chemical reaction is
`underset("reactants")("Sodium carbonate")+underset("reactants")("Ethanoic acid") to underset("products")("Sodium ethanoate")+underset("produts")("Carbon dioxide")+underset("products")"Water"`
Mass of reactants=(10.6+12)=22.6g
Mass of products=(16.4+4.4+1.8)=22.6g
Since the mass of reactants species is equal to the mass of the product species. the data illustrates the law of conservation of mass.
