Question

8.4 g of sodium bicarbonate was added to 6.0 g of acetic acid solution. Carbon dioxide gas was produced
which was allowed to escape while the residue (of sodium acetate and water) was found to weigh 10.0 g.
What is the mass of carbon dioxide which escaped out into the atmosphere, keeping in view the law of
conservation of mass?​

Answer 1

Answer:

20:00 gm is only thing is that my answer is write you can check please

Explanation:

its write

Answer 2

Answer:

Mass of carbon dioxide, CO₂, released = 4.4g

Explanation:

Given,

Mass of sodium bicarbonate, NaHCO₃ = 8.4g

Mass of acetic acid solution, CH₃COOH = 6g

Mass of residue ( sodium acetate and water ) = 10g

Mass of carbon dioxide, CO₂ , escaped =?

When sodium bicarbonate was added to an acetic acid solution, it produced sodium acetate, water and released carbon dioxide.

• NaHCO₃ + CH₃​COOH → CH₃​COONa + CO₂ + H₂​O

Now,

According to the law of conservation of mass,

• Total mass of reactants = Total mass of products

• Mass of NaHCO₃ + Mass of CH₃COOH = Mass of residue ( CH₃COONa + H₂O ) + Mass of CO₂

• 8.4g + 6g = 10g + Mass of CO₂
• Mass of CO₂ = ( 14.4 - 10 ) g = 4.4g

RESULT: Mass of CO₂ released = 4.4g.
