when 4.2 gram of sodium hydrogen carbonate nahco3 is added to the solution of hydrochloric acid HCL weighting 10.0 gram it is observed that 2.2 gram of carbon dioxide is released in to the atmosphere there is do left to behind is found to be weighing 12.12 gram so that there observation are in requirement with law of conservation of mass

answer
Explanation:
weight of NaHCO3 =4.2g
weight of HCl= 10g
weight of CO2= 2.2
weight of residue =12g
according to law of conservation of mass
NaHCO3 + HCl = CO2 +Residue
4.2+10=2.2+12
14.2=14.2
since the massea are aame in before and after the reaction, therefore these observations are in agreement wih law of conservation of mass.
