Question

Dagm of codicem heydoudo. Carbonate
Cala HCO is added to a solution of Hol weighing
log. Assuring the Nla H Cog crepacks.completely.
and the residue left behind is 7.69
how much volume 3 002, is released in
the atmosphere if law of Conservation of
mass holds.​

Answer 1

Answer:

Explanation:

Weight of NaHCO  

3

​  

=4.2g

Weight of HCl=10g

Weight of CO  

2

​  

=2.2g

Weight of residue =12g

According to law of conservation of mass

NaHCO  

3

​  

+HCl=CO  

2

​  

+residue

4.2+10=2.2+12

14.2=14.2  

Since the masses are same before and after the reaction, thus results agree with the law of conservation of mass.

Hence proved.
