When 4.2g of sodium hydrogen carbonate (NaHCO3) is added to a solution of HCl weighing 10.0g, it is observed that 2.2g of CO2 is released into the atmosphere. The residue left behind is found to weigh 12.0g. Show that these observations are in agreement with the laws of conservation of mass.

Q. When 4.2 g of sodium bicarbonate is added to a solution of hydrochloric acid weighing 10g. it is observed that 2.2g of carbon dioxide is released into the atmosphere. The residue behind is found to weigh 12g show that, this observation in are in arrangement with the law of conservation of mass.

Q. When $8.4g$ of $NaHC{O}_3$ is added to a solution of $C{H}_{3}COOH$ weight $20g$.It is observed that $4.4g$ of $C{O}_2$ is released into atmosphere and a residue is left behind.Calculate the mass of residue by applying law of conservation of mass

Q. If $6.3g$ of $NaHC{O}_3$ are added to $10g$ of HCl solution, the residue is found to weigh $12g$. What is the mass of $C{O}_2$ released in the reaction?

Q. If $6.3g$ of $NaHC{O}_3$ are added to $15.0g$ of $C{H}_{3}COOH$ solution, the residue is found to weigh $18.0g$. What is the mass of $C{O}_2$ released in the reaction?

Q. 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 observations are in agreement with the law of conservation of mass.
