Question

One example each of displacement decomposition and combination reaction with explanation

Answer 1

decomposition - Agcl in presence of sunlight breaks into Ag + Cl2 combination= mg +o2- mgo , displacement - cucl2+na- cu+ nacl

Answer 2

in Displacement reaction =

Fe+cuso4 gives feso4+Cu

here iron is highly reactive then coper.

decomposition have three type

1) thermal decomposition = caco3 gives cao+ co2

2) electroloytic = h2o gives h2 +o2

3) photochemical = agcl2 gives ag + cl2

in combinations reaction= cao+h2o gives ca(oh)2
