Question

while verifying the law of conservation of mass a student added 5 gram of sodium carbonate to a test tube containing 14.5 gram of Acetic Acid. the total mass of the reactant is 19.5 gram but the mass of the product after the reaction is only 16.2 gram. the reduction in the mass of the product is due to point a A elimination of CO2 gas. point B E elimination of O2 gas. Liberation of heat. elimination of CO gas.​

Answer 1

Answer:

In the given reaction,

(14g)Sodium carbonate​+(10g)Ethanoic acid​⇒(16.67)(Sodiumethanoate+water)​+(7.33g)Carbondioxidegas​

Total mass of all reactants combined

=14g+10g=24g

Total mass of all the products formed

=16.67g+7.33g=24g.

It is observed that Total mass of all reactants combined =24g= Total mass of all the products formed. Therefore, the given observations are in agreement with the law of conservation of mass.
