Question

Write equations for the reactions of an acid with: a. Zn metal. (b) Na2CO3 (c) NaHCO3 (d) NaOH solution.

Answer 1

-----'by sujeet -----) (a)Zn(s) + 2HCl(aq.) -------------> ZnCl2(aq.) + H2(g)--- b) Na2CO3(s) + 2HCl(aq.) -----------> 2NaCl(aq.) + H2(l) + CO2(g)---- c) NaHCO3(s) + HCl(aq.) ------------> NaCl(aq.) + H2O(l) +CO2(g)----- d) NaOH(aq.) + HCl(aq.) ------------> NaCl(aq.) + H2O(l)

Answer 2

Answer:

2HCl+Zn--------->ZnCl2+H2 (gas)

2HCL+Na2CO3--------->2NaCl+H2CO3

HCl+NaHCO3--------->NaCl+H2CO3

HCl+NaOH--------->NaCl+H2O
