Question

When 6.3 g of sodium bicarbonate are added to 30.0 g of acetic acid solution, the residual solution is found to weigh 33.0 g. The mass of carbon dioxide released in the reaction is (A) 3.0 g (B) 0.91 g (C) 1.91 g (D) 3.3 g

Tardigrade Admin · Accepted Answer

CH3COOH+NaHCO3arrow CH3COONa + H2O+CO2 ∵ Amount of reactants =6.3+30.0=36.3 g ∵ Amount of residual solution =33.0 g ∴ Mass of carbon dioxide released =36.3-33.0 =3.3 g

Q. When $6.3 g$ of sodium bicarbonate are added to $30.0 g$ of acetic acid solution, the residual solution is found to weigh $33.0 g$ . The mass of carbon dioxide released in the reaction is

$3.0 g$

$0.91 g$

$1.91 g$

$3.3 g$

$C H_{3} COO H + N a H C O_{3} \to C H_{3} COON a$ $+ H_{2} O + C O_{2}$
$∵$ Amount of reactants $= 6.3 + 30.0 = 36.3 g$
$∵$ Amount of residual solution $= 33.0 g$
$∴$ Mass of carbon dioxide released $= 36.3 - 33.0$
$= 3.3 g$

Q. When 6.3g of sodium bicarbonate are added to 30.0g of acetic acid solution, the residual solution is found to weigh 33.0g. The mass of carbon dioxide released in the reaction is

3.0g

0.91g

1.91g
