Question

If 6.3 g of NaHCO3 are added to 15.0 g of CH3COOH solution ,the residue is found to weigh 18.0 g. The mass of CO2 released in the reactionis (A) 9.3 g (B) 39 3 g (C) 3.3 g (D) None of these

Tardigrade Admin · Accepted Answer

CH3COOH + NaHCO3 → CH3COONa+H2O+CO2 ↑ CH3COONa+H[2O+CO2 ↑ Mass of reactants = Mass of products 6.3 g+15.0 g=18.0 g+ Mass of CO2 Mass of CO2=6.3 g+15.0 g-18.0 g =3.3 g

Q. If 6.3 g of $N a H C O_{3}$ are added to 15.0 g of $C H_{3} COO H$ solution ,the residue is found to weigh 18.0 g. The mass of $C O_{2}$ released in the reactionis

9.3 g

39 3 g

3.3 g

None of these

$C H_{3} COO H + N a H C O_{3} \to C H_{3} COON a + H_{2} O + C O_{2} ↑$
$C H_{3} COON a + H_{[} 2 O + C O_{2} ↑$
Mass of reactants = Mass of products
$6.3 g + 15.0 g = 18.0 g$ + Mass of $C O_{2}$
Mass of $C O_{2} = 6.3 g + 15.0 g - 18.0 g$
$= 3.3 g$
