Response Details:
  a) Ca(s) + 2H+(aq)   ----------> Ca2+(aq)  + H2(g)
  b) H2O2(aq) + 2I-(aq) + 2H+----------> I2(aq) + 2H2O(l) 
  c)  2I- + Br2(l) -----------> I2(aq) + 2Br-(aq)

Response Details:
a) Ca (s)+ 2HCl (aq) --> CaCl2 (s)+ H2 (g)

Thus , calcium chloride is formed and hydrogen gas liberated

b) H2O2 (l) + KI (aq)+ 2H+ (aq)--> 2H2O (l)+ 2K+ (aq)+ I2 (g)

Thus , Iodine gas is liberated

c) 2KI (aq)+ Br2 (l)--> 2KBr(aq) + I2 (g)

Again , Iodine gas is liberated
