Hey
1) HCl +NaHCO3 ===> NaCl + H2O +CO2
2) HCl +Zn ====> ZnCl2 + H2
3) When egg shell is placed it gets dissolving in HCl.
Hope it helps

a) nahco3 + hcl = nacl +co2+h2o __ we observe that when adding hcl to sodium bicarbonate we will get a common salt ( sodium chloride) with evolution of co2 and h2o.
c) when hcl reacts with crushed egg shells then it will produce a gas which turns lime water milky.

b) zn + hcl = zncl2
b) zn+hcl = zncl2 + h2 _ we will observe that this reaction will end upgiving us zinc chloride and also, it will produce hydgrogen gas.
