Solution

The correct option is D 4.3g
NaHCO3+HClResidue+CO2
Weight of reactants = weight of NaHCO3+weight of HCl
=6.3+10=16.3g
Weight of product = weight of residue+weight of CO2
=12+x
xweight of CO2 released.
a/c to law of conservation of mass
Weight of reactants = weight of products
16.3=12+x
x=16.312=4.3
Weight of CO2 released =4.3g
