Answer #1

1)

2 Li (s) + 2 HI (aq) ---------------> 2 LiI (aq) + H2 (g)

2)

KOH (aq) + HNO3 (aq) -------------> KNO3 (aq)+ H2O (l)

it is neutralization reaction. KOH is base and HNO3 is acid. so salt and water formed.

3)

2 AgNO3 (aq) + CaCl2 (aq) -------------> 2 AgCl (s) + Ca(NO3)2 (aq)

it is precipitate reaction. AgCl (s) is solid precipitate formed

4)

2 C4H10 (l) + 13 O2   (g) ----------------> 8 CO2 + 10 H2O

it is combustion reaction. here CO2 and H2O are produced

5)

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