Question

6. Fill in the blank with appropriate reactant(X)
and products (Y and Z).
Na2CO3 +(X) —→ Na2SO4 + (Y) + (Z)
(a) X =HCI, Y =NaCl, Z=CO2
(b) X =H, SO4, Y =H,O, Z =CO2
(c) X =H,O, Y =H2SO4, Z=CO2
(d) X = NaHCO3, Y =H,O, Z =CO​

Answer 1

Answer:

Na

2

CO

3

+xHCl→2NaCl+CO

2

+H

2

O

Number of chlorine atoms on RHS of equation is 2, which should be the same as no. of atoms on LHS. Hence, the value of x is 2.

Answer 2

Answer:

(b) x = H2SO4 , y = H2O , z = CO2

the reaction is as follows:-

Na2CO3 + H2SO4 ------- Na2SO4 + H2O + CO2
