Question

Write balanced chemical equations for the reaction of dil HCl with: (i) Zn metal (ii) Na2 CO3 (iii) NaOH

Answer 1

(i) Zn metal

2HCL + 2Zn ----> 2ZnCl + H2

(ii) Na2CO3

2HCL + Na2CO3 ------> 2NaCl + H2O + CO2

(iii)NaOH

HCL + NaOH -----> NaCl + H2O

Answer 2

Explanation:

(i) 2HCL+2Zn→ZnCl2+H2

(ii) 2HCL+Na2CO3→2NaCl + H2CO3

(iii) HCL+NaOH→NaCl+H2O
