Answer 2

a) change in colour-

Fe(s)   +             CuSO4(aq)                        = FeSO4 (aq)          +                Cu(s)

iron    copper sulphate (blue)      Ferrous sulphate (green)      copper

b)change in temperature-

Zn(s)   +    H2SO4(aq)    =     ZnSO4(aq)    +     H2(g)

Zinc      sulphuric acid       zinc sulphate       hydrogen

c)formation of precipitate-

AgNO3(aq)    +   KCl(aq)          =          AgCl(precipitate)    +      KNO3(aq)

silver nitrate  potassium chloride   silver chloride( white)     potassium nitrate
