Answer 1

1)MgCO_3(s) + 2HNO_3(aq)=Mg(NO₃)_2(aq)+H₂O +CO₂↑ - Double displacement reaction;

2)Cu(OH)_2(s)+2HNO_3(aq)=Cu(NO₃)_2(aq)+2H₂O - acid-base reaction;

3)NaOH_(aq)+HCl_(aq)=NaCl_(aq)+H₂O - acid-base reaction;

4)PbO_(s) + 2HNO_{3(concentrated)(aq)} = Pb(NO₃)_2(s)↓ + H₂O - double displacement reaction;

5)H₂SO_4(aq) + BaCl_2(aq) = BaSO_4(s)↓ + 2HCl_(aq) - double displacement reaction;
